Types

type Options

type Options struct {
	// Dir contains the directory in which to execute the command.
	// If empty, runs in the current directory.
	Dir string

	// Env allows to override the environment variables to use in the subshell, in the format provided by os.Environ()
	// If empty, uses the environment variables of this process.
	Env []string

	// when set, captures the output and returns it
	IgnoreOutput bool
}

Options defines optional arguments for ShellRunner.RunWith().

type TestRunner

type TestRunner struct {
	// the directory that contains mock executables, ignored if empty
	BinDir string

	// the directory that contains the global Git configuration
	HomeDir string

	// whether to log the output of subshell commands
	Verbose bool `exhaustruct:"optional"`

	// the directory in which this runner executes shell commands
	WorkingDir string
	// contains filtered or unexported fields
}

TestRunner runs shell commands using a customizable environment. This is useful in tests. Possible customizations:

• overide environment variables
• Temporarily override certain shell commands with mock implementations. Temporary mocks are only valid for the next command being run.
