Command Integration Tests

These are tests that run a yamlfmt binary with different combos of commands in a temp directory set up by the test data.

Each test runs by:

• Accepting the absolute path to a binary in the YAMLFMT_BIN environment variable
• Creating a temporary directory
• Copying everything from before in the testdata folder for the given test into the temp directory
• Run the specified command for the given test with the temp directory as the working directory
• Compare goldens for command output and state of the directory
  • If running with a -update flag, simply overwrite all golden files
  • If running normally, compare the golden files to ensure all the files are the same and the content of each file matches

You can run the tests by running make integrationtest which will build the binary and run the tests with it.
