Target the specific tests that are overly reliant on mocks and adjust them to include real dependencies.
Inline Fix for Mocking
In the test located at [FILE]:[LINE], replace the mock implementation of [SPECIFIC FUNCTION] with a real instance of the function. Confirm that the test now interacts with the actual implementation rather than the mock version. Provide a brief explanation of how this change affects the test outcomes and any potential implications for test reliability.
Rewrite Test with Real Dependencies
Rewrite the test for [COMPONENT] to utilize real dependencies instead of mocks. Ensure that the test accurately reflects the actual behavior and interactions of the component in a real environment. Provide a detailed explanation of how the real dependencies improve the test's reliability and any changes made to the test structure.
Scoped Change to Reduce Mocks
Please modify the test located at [FILE]:[LINE] to reduce the number of mocks utilized. Identify and retain only the mocks that are essential for the test to execute successfully. After making the changes, provide a brief explanation of which mocks were removed and why, as well as any impact this has on the test's functionality.
Enforce Real Interaction Format
Update the test for [COMPONENT] to ensure it follows the format: 'Test [NAME] should interact with [REAL DEPENDENCY] and verify [EXPECTED OUTCOME].' Make sure that the test is designed to use real interactions instead of mocks, and provide a brief explanation of how this change improves the reliability of the test. Additionally, outline any potential challenges that may arise from this update and how to address them.
Correct Dependency Imports
Please review the imports in the test file located at [FILE]. Identify any missing real dependencies that should be included and provide a list of the necessary imports. Additionally, suggest ways to minimize the use of mocks in the file, explaining the benefits of each change you recommend.
Confirm that the tests now accurately reflect the application's behavior and that they pass with real dependencies.
Run the Updated Test
Please execute the updated test for [COMPONENT] using real dependencies and verify that it passes successfully. If there are any failures, provide a detailed report outlining the causes of each failure and any relevant error messages. Format the report to include the test results, a summary of the issues encountered, and suggested solutions for each failure.
Show Test Diff
Please provide a detailed diff of the test file before and after the changes related to the use of mocks. Highlight the specific lines where mocks were removed and replaced with real dependencies, and explain the significance of these changes. Additionally, summarize how these modifications improve the test's reliability and accuracy in reflecting the actual behavior of the code.
Replay the Original Test Scenario
Replay the original failing test scenario for [TEST NAME] to verify that it now passes with real interactions. Please document any discrepancies you observe during the replay, including specific details about what differs from the expected outcome. Additionally, provide a summary of the changes made that may have resolved the issue.
Check Edge Case Handling
Please verify that the updated test for [TEST NAME] handles edge cases effectively. Run the test using a variety of inputs, including [EDGE CASE INPUTS], and confirm that the outcomes match the expected results. Provide a summary of any discrepancies and suggest improvements if necessary.
Confirm Test Output State
Please verify the output state of the test for [COMPONENT] after implementing the changes. Analyze the results to ensure that they accurately reflect the expected behavior of the real implementation. Provide a detailed comparison between the actual output and the expected output, highlighting any discrepancies and suggesting potential reasons for any differences observed.
Create artefacts that ensure future tests maintain a balance between mocking and real behavior.
Mocking Best Practices Prompt
Before creating tests for [PROJECT NAME], ensure that mocks are only used when necessary. If a real dependency can be used, it must be included in the tests. Never mock critical interactions that could affect the reliability of the tests. Provide this guideline in a clear and concise format that can be easily referenced during the testing process.
Test Creation Template
Please create a test creation template that includes a detailed checklist for writing tests. The checklist should contain the following items: 1. Identify dependencies, 2. Use real instances where possible, and 3. Limit mocks to non-critical paths. Format the template with clear headings for each section, and provide space for notes or comments on each checklist item to enhance understanding and implementation.
Test Specification Message
Draft a project specification message that clearly states the following: "All tests must validate real behavior. Mocks should only be used when absolutely necessary and must be documented." Ensure the message is concise and emphasizes the importance of maintaining test integrity while providing guidelines for the use of mocks. Format the message in a professional tone suitable for team communication.
Naming Convention for Tests
Establish a naming convention for tests that emphasizes real behavior. The format should be: 'Test[COMPONENT]WithRealDependencies'. Please provide examples of how this naming convention can be applied to different components, and explain why this approach enhances clarity and understanding in test cases.
Self-Check for Test Validity
Please create a self-check request for the agent regarding test validity. The request should include the following: 'Before finalizing tests, confirm that all mocks are necessary and that real dependencies are included where possible.' Ensure that the final output is formatted as a clear checklist that can be easily followed.
Tests may pass with mocks because they do not validate real interactions. Bolt's mocking system can lead to false positives if critical dependencies are not included.
Look for tests that pass without any real interactions. Bolt's output will show if mocks are used excessively, which can mask underlying issues.
Excessive mocking can lead to undetected bugs and unreliable code. Bolt's sandboxed environment may not surface these issues until deployment.
Aim to use real dependencies wherever possible. Bolt's testing framework should reflect actual behavior to ensure reliability in production.
Investigate the test setup and ensure that all necessary real dependencies are included. Bolt may not surface errors related to mocks effectively.
