Overview

Oppia Actions CircleCI Join the chat at https://gitter.im/oppia/oppia-chat

Oppia is an online learning tool that enables anyone to easily create and share interactive activities (called 'explorations'). These activities simulate a one-on-one conversation with a tutor, making it possible for students to learn by doing while getting feedback.

In addition to developing the Oppia platform, the team is also developing and piloting a set of free and effective lessons on basic mathematics. These lessons are targeted at learners who lack access to educational resources.

Oppia is written using Python and AngularJS, and is built on top of Google App Engine.

  • Migrate AngularJS services to Angular 8

    Migrate AngularJS services to Angular 8

    The Oppia project is currently in a hybrid state where we are currently using both Angular 8 and AngularJS. This makes our application slow and bulky, partly because several third-party libraries need to be duplicated (since many of the AngularJS libraries are not compatible with Angular).

    The aim of this issue is to migrate services still using AngularJS to modern Angular 8. The benefits of doing this are:

    • Improved Developer Experience:
      • Developing when the application is a hybrid state opens us to a whole host of complicated errors which are, in some cases, not possible to solve.
      • AngularJS is deprecated, whereas Angular 8 is being actively maintained, and includes lots of new functionality that aids in developing new features.
    • Improved User Experience:
      • When the codebase is completely migrated, the developers can focus their efforts on making new features for the website rather than fixing errors that pop up due to the hybrid state.
      • There will be a decrease in page loading times since we can drop one of the frameworks completely. This will also lead to better application performance in general.

    The instructions on how to migrate a service can be found here. You can use #9984 and #10693 as reference examples.

    Listed below are the files which the Angular team believes can be migrated without major blockers, but please feel free to reach out on Gitter if you run into any problems. If you want to work on any unclaimed service in this tracker, please add a comment in this thread and tag @srijanreddy98, and we'll add you as an assignee. It will be all yours then. This is done so that we don't have any duplication of work.

    Also, after migrating a service, make sure to manually test it. In case you don't know how to access that part of the codebase on the website, please contact your onboarding mentor or @srijanreddy98. Thanks!

  • Test frontend services

    Test frontend services

    This is intended as a starter project for newer contributors but if you're already a contributor for some time, you can help as well.

    NOTE: Please ping @nithusha21 if you have any questions about this issue or would like to be assigned to some part of it.

    In order to prevent future regressions, we want to ensure that all services in our frontend codebase are thoroughly tested. If it's your first time here, please read carefully the guide of how to get started with frontend unit testing: Guide for writing frontend tests. Please use this guide as your helper, all the instructions of how to test properly is in it.

    Also, here is Oppia's wiki page for running the client-side Karma tests.

    The services are separated by three levels of complexity: | Complexity | Easy | Medium | Hard | |:---------------:|:----------------:|:---------------:|:------------------:| | Number of lines | up to 100 lines | up to 250 lines | at least 250 lines |

    Then, it doesn't matter if you're new to unit test or if you're looking for something more challenging, there will be service for you work with.

    Each file is marked with two information that will help you to decide which service to pick. For example:

    • [ ] A - B service-name.service.ts

    A means the service complexity: E for Easy, M for medium and H for Hard. B means if the service has a spec file: Y for Yes and N for No.

    Spec files for services tests consist of the name of the service, followed by .spec.ts or Spec.ts, it depends of the service file name structure:

    • Use .spec.ts for services like: service-name.service.ts
    • Use Spec.ts for services like: ServiceNameService.ts When writing tests, if a spec file already exists for the service you have picked, then edit the existing file. If a spec file isn't present yet, create a new file and name it accordingly. You can also take a look at the existing spec files for different services to get an idea on how to get started.

    Note: We are currently in the process of upgrading AngularJS to Angular. If the service is written in AngularJS, write the test in AngularJS. If the service is written in Angular, write the test in Angular. We would also prefer to cover all Angular files before moving to AngularJS files to prevent extra work during the migration.

    If you'd like to help with this issue, please select a file from the list below, comment on the thread with the file name or any query you'd like to be assigned, and submit a PR when you've completed writing the test. Once the PR is submitted, you can tick the checkboxes.

  • Fixing End-to-End Tests with action.js and waitFor.js

    Fixing End-to-End Tests with action.js and waitFor.js

    Introduction

    Background

    To ensure Oppia remains available and high-quality for our students, we run end-to-end tests on all PRs to check that the site's functionality hasn't been broken. Recently, these tests have begun failing non-deterministically. This frustrates developers and slows their work by incorrectly indicating that developers’ changes are faulty. The goal of this issue is to help resolve these failures, also known as "flakes," by fixing common bad patterns in the current tests.

    Getting Started

    Review the instructions below on how to fix the tests. Then message on the issue thread asking to be assigned to one of the unclaimed files. We will assign you to the file by adding your username next to the file listing. If you have any questions, message on the issue thread, and we'll help you out!

    How to Fix Tests

    For this task, we would like you to pick one of the files listed below and make the following fixes wherever applicable:

    • Instead of calling .click() on an element, use action.click() from action.js
      • Here's an example (link):
        - await element(by.css('.protractor-test-interaction')).click();
        + var testInteractionButton = element(by.css('.protractor-test-interaction'));
        + await action.click('Test Interaction Button', testInteractionButton);
        
      • Sometimes there might be a waitFor statement before the .click() call to make sure the element has loaded before we click it. These can be removed because action.click includes waitFor statements.
    • Instead of calling .getText() on an element, use action.getText() from action.js
      • Here's an example:
        - var text = await element(by.css('.protractor-test-interaction-name')).getText();
        + var interactionNameElement = element(by.css('.protractor-test-interaction-name'));
        + var text = await action.getText('Interaction name element', interactionNameElement);
        
      • Sometimes there might be a waitFor statement before the .getText() call to make sure the element has loaded before we get its text. These can be removed because action.getText includes waitFor statements.
    • Instead of calling .clear() on an element, use action.clear() from action.js
      • Here's an example (link):
        - await stateNameInput.clear();
        + await action.clear('State Name input', stateNameInput);
        

        Note that the diff above is simplified from the linked PR for clarity.

      • Sometimes there might be a waitFor statement before the .clear() call to make sure the element has loaded before we click it. These can be removed because action.clear includes waitFor statements.
    • Instead of calling .sendKeys() on an element, use action.sendKeys() from action.js
      • Here's an example (link):
        - await stateNameInput.sendKeys(name);
        + await action.sendKeys('State Name input', stateNameInput, name);
        

        Note that the diff above is simplified from the linked PR for clarity.

      • Sometimes there might be a waitFor statement before the .sendKeys() call to make sure the element has loaded before we click it. These can be removed because action.sendKeys includes waitFor statements.
    • Use functions from waitFor.js to verify that elements have loaded before interacting with them:
      • Here's an example(link):
        + await waitFor.visibilityOf(languageSelectorLabelElement,
        +  'Language selector label element taking too long to appear');
          expect(await languageSelectorLabelElement.getText()).toBe(
            'Translations for language:');
        
      • Guidelines on finding out which elements need waitFor.js function calls: Please add waitFor statements before any code that requires an element to be present. For example, we need to wait for the element to be present before getting an element's text. In some cases you might not be able to just wait for the element to appear because the test is checking whether that element is present. In these cases, you can wait instead for another element that loads at the same time. Err on the side of adding unnecessary waitFor statements if you're unsure.

  • Finish writing remaining backend tests

    Finish writing remaining backend tests

    Note: As it was getting hard to maintain the long conversastion thread in this issue we have moved this issue to #6550

    This is intended as a starter project for newer contributors.

    We want to implement backend tests for all parts of the code that are missing them. For each file mentioned below, the parts missing can be identified by generating a coverage report (see this wiki page).

    A basic understanding of Python and the codebase would be a suggested requirement for this issue. If you have trouble trying to figure out something in the codebase, take a look at Analyzing the Codebase.

    If you'd like to help with this issue, please select a file from the list below, and comment on the issue that you'd be taking it up, and submit a PR after writing tests for the file. You can also submit a PR which has partially completed tests for a file, if the file is too extensive to test in a single PR. Once the PR is submitted, you can tick the checkboxes.

    (For guidance on how tests should be structured, please see this wiki page.)


    The following files have been tested partially, but do not have 100% coverage. Any of these files can be taken up and tested comprehensively. (Note that the link after each file points to its coverage report on Codecov.)

  • Adding Mypy type annotations to domain folder files

    Adding Mypy type annotations to domain folder files

    This issue will track the type annotation process of all the core/domain/*.py (and their test files). To get started, ask to be assigned to any unclaimed task. Tasks are claimed by adding the username of the claimer to the end of the task, e.g. @example.

    Note: Main code file and its test file must be type-annotated together.

    The general procedure to add type annotations is as follows:

    1. Start with the main code file first.
    2. Remove the file to be annotated from the mypy denylist (i.e. from NOT_FULLY_COVERED_FILES in scripts/run_mypy_checks.py). Run the mypy checks on the code file using python -m scripts.run_mypy_checks --files <path/to/file> to understand all the errors mypy is reporting for this file.
    3. Go over them one by one, and fix them by following the detailed instructions as mentioned in our wiki.
    4. PAY ATTENTION to our guidelines for using type ignores in the codebase.
    5. For testing the changes after annotating all the files, run python -m scripts.run_mypy_checks, which runs the type checks on the entire codebase, and ensure that no errors are being reported.
    6. If errors occur in other files due to you change make sure to also fix those other files.

    Good examples of already annotated files in the codebase:

    1. Check out the core/storage folder.
    2. Ref PR for domain file type annotation: #14034

    If you face problems in understanding a particular case while adding annotations, please go over the tips mentioned in the wiki once, and let us know if you are still stuck!

  • Update docstrings in the python backend code.

    Update docstrings in the python backend code.

    The aim of this issue is to ensure that every backend file is properly documented. The docstrings serve as guidance to developers to help them understand what a class or a method is doing, so they must be written accurately.

    Some useful tips:

    • Please follow our style guide and also the Google Python style guide when writing the docstrings. Make sure to follow the patterns established there as closely as possible, including spacing, capitalization and punctuation.

    • Make sure that the docstrings for every function include Args, Returns, Raises etc. as and when applicable. If there are no args, then you can omit writing Args. Likewise for Returns, Raises etc. as well.

    • If a docstring is not present in the code, or the existing one is too vague for you to understand what's going on just by looking at it, then it should be rewritten to be more clear. You'll often need to read the code as well, and do a grep to find out specific method used in several files and in many other situations.

    • Every argument name under Args and under Returns or Raises should have a data type mentioned along with it. Make separate efforts to analyze their data types as this might be a bit tricky sometimes and there are many chances of getting mistaken. You can, for example, try to run the method/function while temporarily adding raise(type(X)) or logging.info(type(X)) to get the information you need.

    • Leave one line before each of Args, Returns and Raises. Indent any continuation lines by 4 spaces. See existing docstrings for examples.

    • If you feel that some files are absent from the list or some parts of the codebase are unclear or incorrectly factored, please feel free to bring this up!

    Running tests on a specific file

    • Go to the directory where the file is present (say-- if the file is in core directory, perform cd core to reach to the directory).
    • Execute pylint --disable=all --enable=missing-docstring <filename> to perform linter checks on the file. (Note: If you face any problem while running the above command, please comment out this line in .pylintrc locally and uncomment it when pushing your changes).
    • Add docstrings for the lines where you find 'Missing docstrings'.

    Here is the list of files that are required to be updated. Note: Once this issue is complete, we will turn on missing-docstring checks in Oppia's Python linter. Also, take care that some of the test methods/classes have to be excluded from the test files as they don't require docstrings in detail.

    Docstrings for test methods (test_* type) and test classes (*Tests type) don't need docstrings and hence, can be excluded while adding docstrings to the test files. Please add no-docstring-rgx=test_[a-z_]*|[a-zA-Z]*Tests|Test[a-zA-Z]* regex in .pylintrc file under [Basic] section.

  • Migrate directives/controllers to Angular components

    Migrate directives/controllers to Angular components

    This issue aims to migrate directives/controllers written in AngularJS to modern Angular components.

    We would request you to pick up any directive of your choice from core/templates/pages or core/templates/components. After you've picked up a directive, please mention the directive name that you want to take up. We will assign that particular directive to you and keep a track so that there is no duplication of work that goes along. After you're assigned, please go ahead and read this wiki page:https://github.com/oppia/oppia/wiki/Angular-Migration#implementation-details-to-migrate-directives, it has all the steps mentioned clearly that will help you to migrate the directives/controllers.

    Also, make sure all the services that your directive is using are migrated to Angular.

    Please feel free to reach out to @nithusha21 and @darksun27 in case you have any issues.

  • Add

    Add "async" keyword to asynchronous functions that return a promise

    Description

    In order to make it easier for developers to identify asynchronous methods, the following conventions need to be introduced:

    1. Use of "async" keyword in the function definitions.
    2. Use of "Async" added to the end of the function name.

    E.g.

    Before changes:

    fetchClassroomData(classroomUrlFragment: string): Promise<ClassroomData> {
      return new Promise((resolve, reject) => {
        // some asynchronous operation.
      });
    }
    

    After changes:

    async fetchClassroomDataAsync(classroomUrlFragment: string): Promise<ClassroomData> {
      return new Promise((resolve, reject) => {
        // some asynchronous operation.
      });
    }
    

    Note that (1) "async" keyword was added before function name and (2) fetchClassroomData has changed to fetchClassroomDataAsync ("Async" is added to the name).

    For anonymous function definitions, the "async" keyword needs to be added before the "function" keyword. Example:

    Before:

    const getThreads = function() {
      return new Promise((resolve, reject) => {
        // some asynchronous operation.
      });
    }
    

    After:

    const getThreadsAsync = async function() {
      return new Promise((resolve, reject) => {
        // some asynchronous operation.
      });
    }
    

    Tips

    How to find out which functions need this change?

    1. Search for methods that are then-able. You can do a simple search for .then( to reveal asynchronous then-able methods.
    2. Go to the function definition of a function found in step 1 and check if the return type for the function from step 1 is a Promise object. For example, in the fetchClassroomDataAsync function mentioned above, the return type is Promise<ClassroomData, which means that the function returns a Promise object that resolves with a value of type ClassroomData. As long as the return type is of the form Promise<..>, the function can be changed to follow the convention mentioned in the description.
    3. If the function does not have the return type defined, the function definition needs to be updated with the appropriate return type before it can follow the convention mentioned in the description. For information on how to define types, please see "Guide on Defining Types".

    Here are some examples from the code base

    https://github.com/oppia/oppia/blob/e4cd1e8c58232f04e642a6c61133e6716d59bf45/core/templates/services/state-top-answers-stats-backend-api.service.ts#L40-L49

    Steps to follow

    1. On your local setup, add the eslint check @typescript-eslint/promise-function-async (see this).
    2. Run the lint check on the CI on your fork of Oppia or on your local machine. The linter will report all the files that require this change.
    3. Follow the instructions mentioned in the How to find out which functions need this change? section to introduce the new keyword and pattern.

    Important Notes

    1. All the files listed by the eslint check needs to be handled and the PR that fully fixes this issue must also introduce the lint check.
    2. This task can be assigned and worked on only after the following PRs have been merged https://github.com/oppia/oppia/pull/12302, https://github.com/oppia/oppia/pull/12291, https://github.com/oppia/oppia/pull/12194, https://github.com/oppia/oppia/pull/12188, https://github.com/oppia/oppia/pull/12164, https://github.com/oppia/oppia/pull/12151, https://github.com/oppia/oppia/pull/12020.
    3. The assignee for this task must ensure that the async / ..Async pattern is introduced across the codebase in their PR.

    [BUG]: Disable blog post Publish button in the /blog-post-editor page, when any draft/published blog post with same title already exists.

    Describe the bug

    Currently, if we try to save a blog post draft or publish a blog post with a title such that it already exists in the drafts or the published section, then we get an error alert that we cannot save/publish a blog post with the title already exists. but if the blog post with the same title already exists the Publish or save draft button must be disabled with an error message in red color below that button that the title needs to be changed!

    Steps To Reproduce

    1. go to blog-dashboard and create a new blog post
    2. add the blog post title such that a blog post with the same title already exists.
    3. try to save/publish it, you will see an error alert

    Expected Behavior

    the Save/Publish button must be disabled with an error message below it.
