Types

type CtyJsonOutput 

type CtyJsonOutput struct {
	Value map[string]interface{}
	Type  interface{}
}

When you convert a cty value to JSON, if any of that types are not yet known (i.e., are labeled as DynamicPseudoType), cty's Marshall method will write the type information to a type field and the actual value to a value field. This struct is used to capture that information so when we parse the JSON back into a Go struct, we can pull out just the Value field we need.

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 InputFileKeyNotFound 

type InputFileKeyNotFound struct {
	FilePath string
	Key      string
}

InputFileKeyNotFound occurs when tfvar file does not contain a value for the key specified in the function call

func (InputFileKeyNotFound) Error 

func (err InputFileKeyNotFound) Error() string

type Options 

type Options struct {
	TerraformBinary string // Name of the binary that will be used
	TerraformDir    string // The path to the folder where the Terraform code is defined.

	// The vars to pass to Terraform commands using the -var option. Note that terraform does not support passing `null`
	// as a variable value through the command line. That is, if you use `map[string]interface{}{"foo": nil}` as `Vars`,
	// this will translate to the string literal `"null"` being assigned to the variable `foo`. However, nulls in
	// lists and maps/objects are supported. E.g., the following var will be set as expected (`{ bar = null }`:
	// map[string]interface{}{
	//     "foo": map[string]interface{}{"bar": nil},
	// }
	Vars map[string]interface{}

	VarFiles                 []string               // The var file paths to pass to Terraform commands using -var-file option.

}

Options for running Terraform commands

func GetCommonOptions 

func GetCommonOptions(options *Options, args ...string) (*Options, []string)

GetCommonOptions extracts commons terraform options

func WithDefaultRetryableErrors 

func WithDefaultRetryableErrors(t testing.TestingT, originalOptions *Options) *Options

WithDefaultRetryableErrors makes a copy of the Options object and returns an updated object with sensible defaults for retryable errors. The included retryable errors are typical errors that most terraform modules encounter during testing, and are known to self resolve upon retrying. This will fail the test if there are any errors in the cloning process.

func (*Options) Clone 

func (options *Options) Clone() (*Options, error)

Clone makes a deep copy of most fields on the Options object and returns it.

NOTE: options.SshAgent and options.Logger CANNOT be deep copied (e.g., the SshAgent struct contains channels and listeners that can't be meaningfully copied), so the original values are retained.

type OutputKeyNotFound 

type OutputKeyNotFound string

OutputKeyNotFound occurs when terraform output does not contain a value for the key specified in the function call

func (OutputKeyNotFound) Error 

func (err OutputKeyNotFound) Error() string

type OutputValueNotList 

type OutputValueNotList struct {
	Value interface{}
}

OutputValueNotList occurs when casting a found output value to a list of interfaces fails

func (OutputValueNotList) Error 

func (err OutputValueNotList) Error() string

type OutputValueNotMap 

type OutputValueNotMap struct {
	Value interface{}
}

OutputValueNotMap occures when casting a found output value to a map fails

func (OutputValueNotMap) Error 

func (err OutputValueNotMap) Error() string

type PanicWhileParsingVarFile 

type PanicWhileParsingVarFile struct {
	ConfigFile     string
	RecoveredValue interface{}
}

PanicWhileParsingVarFile is returned when the HCL parsing routine panics due to errors.

func (PanicWhileParsingVarFile) Error 

func (err PanicWhileParsingVarFile) Error() string

type PlanStruct 

type PlanStruct struct {
	// The raw representation of the plan. See
	// https://www.terraform.io/docs/internals/json-format.html#plan-representation for details on the structure of the
	// plan output.
	RawPlan tfjson.Plan

	// A map that maps full resource addresses (e.g., module.foo.null_resource.test) to the planned values of that
	// resource.
	ResourcePlannedValuesMap map[string]*tfjson.StateResource

	// A map that maps full resource addresses (e.g., module.foo.null_resource.test) to the planned actions terraform
	// will take on that resource.
	ResourceChangesMap map[string]*tfjson.ResourceChange
}

PlanStruct is a Go Struct representation of the plan object returned from Terraform (after running `terraform show`). Unlike the raw plan representation returned by terraform-json, this struct provides a map that maps the resource addresses to the changes and planned values to make it easier to navigate the raw plan struct.

func InitAndPlanAndShowWithStruct 

func InitAndPlanAndShowWithStruct(t testing.TestingT, options *Options) *PlanStruct

InitAndPlanAndShowWithStruct runs terraform init, then terraform plan, and then terraform show with the given options, and parses the json result into a go struct. This will fail the test if there is an error in the command.

func InitAndPlanAndShowWithStructE 

func InitAndPlanAndShowWithStructE(t testing.TestingT, options *Options) (*PlanStruct, error)

InitAndPlanAndShowWithStructE runs terraform init, then terraform plan, and then terraform show with the given options, and parses the json result into a go struct.

func InitAndPlanAndShowWithStructNoLogTempPlanFile 

func InitAndPlanAndShowWithStructNoLogTempPlanFile(t testing.TestingT, options *Options) *PlanStruct

InitAndPlanAndShowWithStructNoLog runs InitAndPlanAndShowWithStruct without logging and also by allocating a temporary plan file destination that is discarded before returning the struct.

func ParsePlanJSON 

func ParsePlanJSON(jsonStr string) (*PlanStruct, error)

ParsePlanJSON takes in the json string representation of the terraform plan and returns a go struct representation for easy introspection.

func ShowWithStruct 

func ShowWithStruct(t testing.TestingT, options *Options) *PlanStruct

func ShowWithStructE 

func ShowWithStructE(t testing.TestingT, options *Options) (*PlanStruct, error)

type ResourceCount 

type ResourceCount struct {
	Add     int
	Change  int
	Destroy int
}

ResourceCount represents counts of resources affected by terraform apply/plan/destroy command.

func GetResourceCount 

func GetResourceCount(t testing.TestingT, cmdout string) *ResourceCount

GetResourceCount parses stdout/stderr of apply/plan/destroy commands and returns number of affected resources. This will fail the test if given stdout/stderr isn't a valid output of apply/plan/destroy.

func GetResourceCountE 

func GetResourceCountE(t testing.TestingT, cmdout string) (*ResourceCount, error)

GetResourceCountE parses stdout/stderr of apply/plan/destroy commands and returns number of affected resources.

type TgInvalidBinary 

type TgInvalidBinary string

TgInvalidBinary occurs when a terragrunt function is called and the TerraformBinary is set to a value other than terragrunt

func (TgInvalidBinary) Error 

func (err TgInvalidBinary) Error() string

type UnexpectedOutputType 

type UnexpectedOutputType struct {
	Key          string
	ExpectedType string
	ActualType   string
}

UnexpectedOutputType is an error that occurs when the output is not of the type we expect

func (UnexpectedOutputType) Error 

func (err UnexpectedOutputType) Error() string

type UnsupportedDefaultWorkspaceDeletion 

type UnsupportedDefaultWorkspaceDeletion struct{}

UnsupportedDefaultWorkspaceDeletion is returned when user tries to delete the workspace "default"

func (err *UnsupportedDefaultWorkspaceDeletion) Error() string

type VarFileNotFound 

type VarFileNotFound struct {
