### Get Evolve Help

Source: https://github.com/andreasmatthias/pdfpages/blob/main/test/development.org

Displays the help message for the 'evolve' tool, outlining its available commands and options.

```bash
# evolve help
```

--------------------------------

### Prepare Test Environment

Source: https://github.com/andreasmatthias/pdfpages/blob/main/test/development.org

Navigates to the test directory and executes the 'make' command to prepare necessary PDF files for testing.

```bash
cd ./test/
make
```

--------------------------------

### Run a Specific Test File

Source: https://github.com/andreasmatthias/pdfpages/blob/main/test/development.org

Executes a single test file (e.g., 'my-test.lvt') using all configured TeX-engines.

```bash
# evolve check my-test
```

--------------------------------

### Diff Test PDF Files Visually

Source: https://github.com/andreasmatthias/pdfpages/blob/main/test/development.org

Performs a visual comparison of PDF output files for a test, providing a more user-friendly diff than log file comparison.

```bash
# evolve diff my-test --pdf
```

--------------------------------

### Save Test Results (TLG Files)

Source: https://github.com/andreasmatthias/pdfpages/blob/main/test/development.org

Creates '.tlg' files, which represent the log files of successful test runs, for a given test file.

```bash
# evolve save my-test
```

--------------------------------

### Diff Test Log Files

Source: https://github.com/andreasmatthias/pdfpages/blob/main/test/development.org

Compares the log files of a test run against pre-existing '.tlg' files to identify differences.

```bash
# evolve diff my-test --setting lualatex
```

--------------------------------

### Run Test with Specific Setting

Source: https://github.com/andreasmatthias/pdfpages/blob/main/test/development.org

Restricts the execution of a test file to a single specified TeX-engine setting (e.g., 'lualatex').

```bash
# evolve check my-test --setting lualatex
```

--------------------------------

### Save Test Results for Specific Setting

Source: https://github.com/andreasmatthias/pdfpages/blob/main/test/development.org

Creates '.tlg' files for a test file using only a specific TeX-engine setting.

```bash
# evolve save my-test --setting lualatex
```

--------------------------------

### Run All Tests After Overwriting

Source: https://github.com/andreasmatthias/pdfpages/blob/main/test/development.org

Executes all tests after '.tlg' files have been potentially overwritten, useful for verifying changes against newly generated expected results.

```bash
# evolve check
```

--------------------------------

### Overwrite All TLG Files

Source: https://github.com/andreasmatthias/pdfpages/blob/main/test/development.org

Overwrites all existing '.tlg' files. This is typically used after checking out an older commit to regenerate expected PDF files.

```bash
# evolve save --overwrite-all
```
