Tests that always pass can mask critical issues in your codebase, leading to undetected bugs. This can result in unreliable software and increased maintenance costs. These prompts help developers identify and correct faulty test logic to ensure robust and accurate testing. Built across 4 distinct stages covering Diagnose the Wall, Isolate and Fix, Verify the Resolution and more, this guide gives you one expert prompt per step so you never have to write from scratch or guess what the AI needs. The prompts work in ChatGPT, Claude, and Gemini and are designed to get usable output on the first try.

Provide a brief explanation for each rewritten test case, detailing why it will now correctly identify faults in the implementation.

Isolate and Fix

Strengthen Assertions

Please review the following test cases: [PASTE TEST CASES]. For each test case, enhance the assertions to ensure they accurately reflect the expected outcomes. Provide specific examples of improved assertions, explaining why each enhancement is necessary and how it better captures the expected behavior. Aim for clarity and precision in your examples, and ensure that they are easy to understand for someone reviewing the tests.

Isolate and Fix

Increase Test Coverage

Identify any untested paths in the following functions: [PASTE FUNCTION NAMES]. For each untested path, write detailed additional test cases that cover these scenarios, ensuring that all edge cases are included. Each test case should specify the input values, expected outputs, and any relevant conditions or assumptions. Additionally, provide a brief explanation of why each test case is necessary for comprehensive testing of the functions.

Isolate and Fix

Adjust Mocked Dependencies

Please review the following test cases: [PASTE TEST CASES]. Modify the mocked dependencies in each case to better align with real-world scenarios, ensuring that the adjustments enhance the accuracy and reliability of the tests. For each modification, provide a detailed explanation of the changes made, including the rationale behind each adjustment and how it improves the test's effectiveness. Aim for clarity and thoroughness in your explanations.

Isolate and Fix

Refine Test Setup

Revise the setup and teardown processes for the following test cases: [PASTE TEST CASES]. Ensure that the adjustments you make will prevent false positives and enhance the reliability of the tests. Please provide a detailed explanation of each adjustment, including the rationale behind the changes, how they improve the test outcomes, and any potential impact on the overall testing framework. Additionally, outline any new dependencies or configurations that may be required as a result of these changes.

Isolate and Fix

Verify the Resolution

Ensure the changes have resolved the issue and tests now behave as expected.

Run Corrected Tests

Please execute the following revised test cases: [PASTE TEST CASES]. I need you to confirm that each test case fails when the implementation is incorrect and passes when it is correct. Additionally, provide a summary of the results, indicating which tests passed and which failed, along with any relevant error messages or issues encountered during the execution.

Verify the Resolution

Check Assertion Validity

Verify the validity of the updated assertions in the following test cases: [PASTE TEST CASES]. Analyze each assertion to ensure it accurately reflects the expected outcomes based on the test criteria. After reviewing, provide a detailed summary of the results, highlighting any discrepancies, confirming valid assertions, and suggesting any necessary corrections or improvements. Include specific examples from the test cases to support your findings.
