E2E Test: Student Completes Quiz Successfully

by Alex Johnson 46 views

In this article, we'll explore how to perform an end-to-end (E2E) test to ensure a student can successfully complete a quiz. This test covers the entire process, from logging in to viewing the submission status. We'll delve into the specifics of setting up the test, executing it, and verifying the expected outcomes. The goal is to confirm that all components of the quiz system work together seamlessly to provide a smooth user experience.

Understanding End-to-End Testing

End-to-End (E2E) testing is a methodology used to verify the entire flow of an application from start to finish. It aims to simulate a real user scenario and validate that all the integrated components of the system work as expected. Unlike unit tests, which focus on individual components, E2E tests cover the entire application stack, including the user interface, database, network, and any other dependencies. When it comes to ensuring software quality, E2E testing plays a vital role in identifying potential issues early in the development cycle. This helps to reduce the risk of releasing software with critical bugs or functionality problems. By simulating real user interactions, E2E tests help to ensure that the application is working correctly and meets the needs of the users.

For our specific scenario of a student completing a quiz, the E2E test would involve starting with the login process, navigating to the quiz, answering the questions, submitting the quiz, and finally verifying that the submission has been recorded correctly. Each of these steps is a crucial part of the overall process, and E2E testing ensures that they all work together harmoniously. By covering the entire flow, we can identify issues that might not be apparent when testing individual components in isolation. For example, there might be a problem with the integration between the user interface and the database, which would only be detected through E2E testing. In essence, E2E testing provides a comprehensive assessment of the application's functionality, ensuring that it meets the required standards of quality and reliability.

Test Case: Happy Path for Quiz Completion

This happy path test case verifies the scenario where a student successfully completes a quiz without encountering any errors. It's designed to validate the core functionality of the quiz system, confirming that a student can log in, access the quiz, answer questions, submit the quiz, and have their attempt correctly stored in the database. We will be performing several steps including logging into the application with valid student credentials. Next we have to navigate to the quiz that we want to take and ensure that the quiz is accessible and loads correctly. After this, we will answer all the questions in the quiz. The answers can be pre-defined to ensure consistency in the test results. We will submit the quiz after answering all questions and then wait for the confirmation message or page indicating successful submission. Finally we have to verify that the attempt has been recorded in the database with the correct student ID, quiz ID, and answers. We will also check the UI to ensure that the submission status is displayed correctly to the student. By following this happy path, we can ensure that the basic functionality of the quiz system is working as expected and that students can complete quizzes without encountering any issues. This forms the foundation for further testing, including negative test cases and edge cases.

Preconditions

Before executing the test, ensure the following preconditions are met:

  • A valid student account exists.
  • A quiz is available and accessible to students.
  • The database is running and accessible.
  • The application is deployed and running in a test environment.

These preconditions are essential to ensure that the test environment is properly set up and ready for the E2E test to be executed. Without a valid student account, it would not be possible to log in and access the quiz. Similarly, if there is no quiz available or if it is not accessible to students, there would be nothing to test. The database must be running and accessible to ensure that the quiz attempts can be recorded correctly. Finally, the application must be deployed and running in a test environment to simulate the real user experience and ensure that the test results are accurate. By verifying these preconditions, we can minimize the risk of encountering unexpected issues during the test execution and ensure that the test results are reliable.

Step-by-Step Test Execution

Let's walk through the detailed steps of executing the E2E test. Each step is crucial for simulating the user's interaction with the quiz system and verifying the expected outcomes. First you must Login: Open the application in a web browser and enter the valid student credentials (username and password) to log in. Verify that the login is successful and that the student is redirected to the appropriate dashboard or home page. Next, you must Select Quiz: Navigate to the page containing the list of available quizzes and select the quiz to be attempted. Ensure that the quiz loads correctly and that all questions are displayed properly. Now you can Answer Questions: Answer all the questions in the quiz. The answers can be pre-defined to ensure consistency in the test results. Make sure that the answers are correctly entered and that all questions are answered before proceeding. Next is the Submit: After answering all questions, submit the quiz. Wait for the confirmation message or page indicating successful submission. Verify that the submission is successful and that the student is redirected to the results page or back to the dashboard. And finally, you must Verify Attempt Stored: Check the database to ensure that the attempt has been recorded with the correct student ID, quiz ID, and answers. Also, check the UI to ensure that the submission status is displayed correctly to the student. By following these steps, we can simulate the entire process of a student completing a quiz and verify that all components of the quiz system are working together seamlessly. This helps to ensure that the quiz system is reliable and provides a smooth user experience for the students.

Step 1: Login

  1. Open the application in a web browser.
  2. Enter valid student credentials (username and password).
  3. Verify successful login and redirection to the student dashboard.

Step 2: Select Quiz

  1. Navigate to the quiz list.
  2. Select the desired quiz.
  3. Confirm the quiz loads correctly.

Step 3: Answer Questions

  1. Answer all questions in the quiz.
  2. Ensure answers are correctly entered.

Step 4: Submit

  1. Submit the quiz.
  2. Wait for the confirmation message.
  3. Verify successful submission.

Step 5: Verify Attempt Stored

  1. Check the database for the attempt record.
  2. Verify student ID, quiz ID, and answers.
  3. Check the UI for the correct submission status.

Expected Results

  • Database: An attempt row should be present in the database with the correct student ID, quiz ID, and answers.
  • UI: The UI should display a submission status indicating that the quiz has been successfully submitted.

These expected results are crucial for determining whether the E2E test has passed or failed. The presence of an attempt row in the database confirms that the quiz submission has been recorded correctly. This ensures that the student's attempt is stored for grading and analysis purposes. The correct student ID, quiz ID, and answers must be verified to ensure that the data is accurate and consistent. In addition to the database verification, the UI should also display a submission status indicating that the quiz has been successfully submitted. This provides immediate feedback to the student, confirming that their submission has been received and processed. By verifying both the database and the UI, we can ensure that the entire quiz submission process is working as expected and that the student has a smooth and reliable experience.

Conclusion

By following this E2E test, you can ensure that the core functionality of your quiz system is working correctly. This test covers the entire process, from login to submission, providing a comprehensive assessment of the system's reliability. Performing these tests regularly can help identify and resolve issues early, leading to a more stable and user-friendly application.
