Functions

func Apply

func Apply(t *testing.T, options *Options) string

Apply runs terraform apply with the given options and return stdout/stderr. Note that this method does NOT call destroy and assumes the caller is responsible for cleaning up any resources created by running apply.

func ApplyE

func ApplyE(t *testing.T, options *Options) (string, error)

ApplyE runs terraform apply with the given options and return stdout/stderr. Note that this method does NOT call destroy and assumes the caller is responsible for cleaning up any resources created by running apply.
