# Skill: Add Missing Unit Test You are tasked with adding a new unit test for a class that currently lacks one, or adding a new test case to an existing test file, to improve code coverage and reliability. ## Objective Add a new unit test for a class that currently lacks one, or add a new test case to an existing test file, to improve code coverage and reliability. ## Workflow Instructions ### 1. Identify Target - Choose a class in `src/` that has complex logic but logic coverage is missing or incomplete. ### 2. Establish Baseline - Run `./gradlew testClasses` to compile all sources (production and test) and ensure the project is in a valid state. - Run `./gradlew verifyPlugin` to ensure no plugin verification issues exist. - Run `./gradlew test` (or specific test if it exists) to establish current pass/fail status. - Run tests with Kover (`./gradlew koverHtmlReport` or `./gradlew koverXmlReport`) to determine current coverage percentage for target class. ### 3. Implement Test - Create a new test class (`[ClassName]Test`) in `testSrc/` if it doesn't exist. - Add test cases to cover specific methods, edge cases, and branches. - Ensure the test follows project testing conventions (naming, mocking, assertions). ### 4. Verify - Run `./gradlew testClasses` to ensure new test compiles. - Run new test (and related tests) to ensure it passes. - Run `./gradlew verifyPlugin` to ensure no regressions in plugin verification. - Run Kover again to confirm coverage improvement. ### 5. Report & Review - Summarize test added and coverage improvement. - **Test Location:** Explicitly state *where* in the IDE user should go to test changed functionality (e.g., "Run the new test file `[TestFileName]`"). - **Action:** Ask user to review new test closely. Validate that code being tested is actively used (e.g., check that it is not dead code/0 references). - **Do not commit or push.** - Provide a suggested Git commit message, **explicitly including the Kover coverage improvement**: - Example Pattern: `Add unit tests for [Class Name]. Coverage verified using Kover. Coverage improvement: [Class Name]: ~[X]% line coverage ([Y] covered, [Z] uncovered).`
