Pull request for issue #7
This commit adds the results of running mutation tests using Selene. The tests were run on all packages in the `internal` directory. ## Summary | Package | Score | Surviving Mutations | Notes | | ------------------- | -------- | ------------------- | ---------------------- | | `internal/query` | 100% | 0 | Excellent test coverage. | | `internal/collector`| 90.62% | 3 | Good coverage, but some error paths are not tested. | | `internal/shell` | 57.14% | 3 | Needs improvement, several mutations survived. | | `internal/database` | N/A | 0 | No test coverage. | | `internal/pkgpattern`| N/A | 0 | No test coverage. | ## Surviving Mutations ### `internal/collector` 1. `Logical-internal/collector/all_code.go:45:21`: The test suite does not cover the error handling for `os.ReadFile`. 2. `Logical-internal/collector/all_coverage.go:202:25`: Missing test for a logical operator. 3. `Comparison-internal/collector/all_coverage.go:205:27`: Missing test for a comparison. ### `internal/shell` 1. `Comparison-internal/shell/shell.go:51:11`: Missing test for a comparison. 2. `Comparison-internal/shell/shell.go:57:18`: Missing test for a comparison. 3. `Comparison-internal/shell/shell.go:79:43`: Missing test for a comparison. ## Recommendations 1. Add tests to cover the surviving mutations in `internal/collector` and `internal/shell`. 2. Add tests for the `internal/database` and `internal/pkgpattern` packages.

This commit improves the test coverage of the project based on the results of mutation testing. I have added new tests for the `internal/collector`, `internal/database`, and `internal/pkgpattern` packages. Here is a summary of the changes: * **`internal/collector`**: Added a test for file read errors in `all_code_test.go` and a new test file, `function_finder_test.go`, to specifically test the `functionFinder` and its `findFunction` method. This improved the mutation test score from 90.62% to 93.75%. * **`internal/database`**: Added a new test file, `data_test.go`, with tests for the `CreateTables` and `PersistDatabase` functions. I also refactored the `CreateTables` function to accept the DDL string as an argument, which makes it easier to test. * **`internal/pkgpattern`**: Added a table-driven test for the `ListPackages` function to cover more cases. * **`internal/shell`**: I was unable to improve the test coverage for this package due to the tests timing out. I suspect the issue is with the `readline` library, but I was unable to find a solution. * **`.gitignore`**: Added the `out/` directory to the `.gitignore` file to avoid committing build artifacts. ### Outstanding Issues * **`internal/shell`**: The mutation tests for this package are timing out. I have reverted the changes to the tests to avoid leaving them in a broken state. * **`internal/pkgpattern`**: There is still one surviving mutation in this package. I have tried several approaches to kill it, but I have not been successful.

This submission contains the results of running mutation tests on the codebase. I have analyzed the results and provided a detailed summary in the commit message. I have also updated the
.gitignorefile to exclude build artifacts.Fixes #10
