Variables

var (
	// LookPath is a function that performs `exec.LookPath`.
	// The sole purpose of this variable is to be able to mock calls to the exec module during tests.
	//
	// LookPath searches for an executable named file in the directories named by the PATH environment variable.
	// If file contains a slash, it is tried directly and the PATH is not consulted.
	// The result may be an absolute path or a path relative to the current directory.
	// (from exec.LookPath docstring)
	LookPath = DefaultLookPath

	// CommandOutput is a function that performs `exec.Command` in a certain dir, returning the command's Output().
	// The sole purpose of this variable is to be able to mock calls to the exec module during tests.
	CommandOutput = DefaultCommandOutput

	// CommandCombinedOutput is a function that performs `exec.Command` in a certain dir, returning the command's CombinedOutput().
	// The sole purpose of this variable is to be able to mock calls to the exec module during tests.
	CommandCombinedOutput = DefaultCommandCombinedOutput

	// PipelineOutput is a function that allows executing a pipeline of commands,
	// i.e. commands like `ls -l | grep exec | wc -l`
	PipelineOutput = DefaultPipelineOutput
