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.

func Destroy

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

Destroy runs terraform destroy with the given options and return stdout/stderr.

func DestroyE

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

DestroyE runs terraform destroy with the given options and return stdout/stderr.

func FormatArgs

func FormatArgs(customVars map[string]interface{}, args ...string) []string

FormatArgs converts the inputs to a format palatable to terraform. This includes converting the given vars to the format the Terraform CLI expects (-var key=value).

func FormatTerraformVarsAsArgs

func FormatTerraformVarsAsArgs(vars map[string]interface{}) []string

FormatTerraformVarsAsArgs formats the given variables as command-line args for Terraform (e.g. of the format -var key=value).

func Get

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

Get calls terraform get and return stdout/stderr.

func GetE

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

GetE calls terraform get and return stdout/stderr.

func Init

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

Init calls terraform init and return stdout/stderr.

func InitAndApply

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

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

func InitAndApplyE

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

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

func InitE

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

InitE calls terraform init and return stdout/stderr.

func Output

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

Output calls terraform output for the given variable and return its value.

func OutputE

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

OutputE calls terraform output for the given variable and return its value.

func OutputRequired

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

OutputRequired calls terraform output for the given variable and return its value. If the value is empty, fail the test.

func OutputRequiredE

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

OutputRequiredE calls terraform output for the given variable and return its value. If the value is empty, return an error.

func RunTerraformCommand

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

RunTerraformCommand runs terraform with the given arguments and options and return stdout/stderr.

func RunTerraformCommandE

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

RunTerraformCommandE runs terraform with the given arguments and options and return stdout/stderr.

Types

type EmptyOutput

type EmptyOutput string

EmptyOutput is an error that occurs when an output is empty.

func (EmptyOutput) Error

func (outputName EmptyOutput) Error() string

type Options

type Options struct {
	TerraformDir             string                 // The path to the folder where the Terraform code is defined.
	Vars                     map[string]interface{} // The vars to pass to Terraform commands using the -var option.
	EnvVars                  map[string]string      // Environment variables to set when running Terraform
	RetryableTerraformErrors map[string]string      // If Terraform apply fails with one of these (transient) errors, retry. The keys are text to look for in the error and the message is what to display to a user if that error is found.
	MaxRetries               int                    // Maximum number of times to retry errors matching RetryableTerraformErrors
	TimeBetweenRetries       time.Duration          // The amount of time to wait between retries
	Upgrade                  bool                   // Whether the -upgrade flag of the terraform init command should be set to true or not
	NoColor                  bool                   // Whether the -no-color flag will be set for any Terraform command or not
}
