Mastering Mobile App Testing Strategies: Easy Quiz Quiz

1. Understanding Unit Testing

   Which of the following best describes a unit test in the context of software development?

   1. A test that checks individual pieces of code like functions or methods in isolation.
   2. A test that checks the overall performance of the entire application.
   3. A test that only runs once before deployment.
   4. A test completed manually by a team member.
   5. A test that compares two different programming languages.

2. Purpose of Snapshot Tests

   What is the primary goal of snapshot testing in mobile app development?

   1. To check that the user interface matches a previously stored version.
   2. To monitor network traffic while the app runs.
   3. To measure the speed of background processes.
   4. To test code on different operating systems.
   5. To verify database connection strings.

3. Role of Manual Testing

   In a typical release process, why might manual testing still be required even with many automated tests?

   1. Because some issues are easier for humans to notice, such as visual glitches.
   2. Because automated tools cannot run on mobile devices.
   3. Because manual tests are always faster than automated tests.
   4. Because code changes don't affect app behavior.
   5. Because only manual tests can catch spelling errors in code.

4. Scaling UI Tests

   What is a common challenge when increasing the number of UI tests in a mobile app project?

   1. Managing test failures and identifying the root cause of breakages.
   2. Ensuring the app supports multiple languages.
   3. Reducing server downtime.
   4. Shortening code review times.
   5. Synchronizing team calendars.

5. Automated vs. Manual Testing

   Which of the following is an advantage of automated tests over manual tests?

   1. Automated tests can be run repeatedly without human intervention.
   2. Automated tests do not require any initial setup.
   3. Manual tests run faster than automated tests.
   4. Automated tests never fail.
   5. Manual tests can check code syntax automatically.

6. Test Coverage Improvement

   Why is improving unit test coverage important for a development team?

   1. It helps detect bugs early by testing more parts of the codebase.
   2. It increases the number of developers in the team.
   3. It guarantees zero bugs in the app.
   4. It shortens the app's startup time.
   5. It automatically publishes the app after each test.

7. Reverse Dependency Tree

   When developers run tests affected by their changes, what is the reverse dependency tree used for?

   1. To identify which tests are related to the changed files.
   2. To reverse the order of test execution.
   3. To remove unnecessary lines of code.
   4. To track user login locations.
   5. To schedule team meetings.

8. Types of Tests

   Which type of test is MOST likely to be written and maintained by a Quality Assurance (QA) team?

   1. User Interface (UI) tests that simulate user interactions.
   2. Database integration scripts.
   3. Memory usage analysis.
   4. Automated code formatting.
   5. Application logging setup.

9. Reducing Manual Testing

   How can adding more UI test cases help reduce the need for manual testing before a release?

   1. By automatically checking that app screens work as expected without human input.
   2. By increasing the size of the development team.
   3. By lowering the overall complexity of the app.
   4. By eliminating the need for any form of documentation.
   5. By slowing down the continuous integration process.

10. Testing Workflow Productivity

    What is one productivity hurdle developers may face when using snapshot tests?

    1. Accepting new or changed snapshots efficiently after updates.
    2. Writing code in the wrong programming language.
    3. Merging unrelated pull requests together.
    4. Forgetting to update team calendars.
    5. Storing tests in external hard drives only.
