Starport Integration Tests

The Starport integration tests build a new application and run all Starport commands to check the Starport code integrity. The runners and helper methods are located in this current folder. The test commands are split into folders, for better concurrency, each folder is a parallel job into the CI workflow. To create a new one, we only need to create a new folder. This will be automatically detected and added into the PR CI checks, or we can only create new tests into an existing folder or file.

Running synchronously all integration tests can be very slow. The command below can run everything:

go test -v -timeout 120m ./integration

Or you can just run a specific test folder, like the list types test

go test -v -timeout 120m ./integration/list

Usage

• Create a new env and scaffold an empty chain:

var (
    env  = envtest.New(t)
    path = env.Scaffold("github.com/test/blog")
)

• Now, you can use the env to run the starport commands and check the success status:

env.Must(env.Exec("create a list with bool",
    step.NewSteps(step.New(
        step.Exec(envtest.IgniteApp, "s", "list", "--yes", "document", "signed:bool"),
        step.Workdir(path),
    )),
))
env.EnsureAppIsSteady(path)

• To check if the command returns an error, you can add the envtest.ExecShouldError() step:

env.Must(env.Exec("should prevent creating a list with duplicated fields",
    step.NewSteps(step.New(
        step.Exec(envtest.IgniteApp, "s", "list", "--yes", "company", "name", "name"),
        step.Workdir(path),
    )),
    envtest.ExecShouldError(),
))
env.EnsureAppIsSteady(path)

Functions

func Contains

func Contains(s, partial string) bool

func HasTestVerboseFlag

func HasTestVerboseFlag() bool

Types

type App

type App struct {
	// contains filtered or unexported fields
}

func (App) Binary

func (a App) Binary() string

Binary returns the binary name of the app. Can be executed directly w/o any path after app.Serve is called, since it should be in the $PATH.

func (App) EditConfig

func (a App) EditConfig(apply func(*chainconfig.Config))

func (App) EnableFaucet

func (a App) EnableFaucet(coins, coinsMax []string) (faucetAddr string)

EnableFaucet enables faucet by finding a random port for the app faucet and update config.yml with this port and provided coins options.

func (App) EnsureSteady

func (a App) EnsureSteady()

EnsureSteady ensures that app living at the path can compile and its tests are passing.

func (App) RandomizeServerPorts

func (a App) RandomizeServerPorts() chainconfig.Host

RandomizeServerPorts randomizes server ports for the app at path, updates its config.yml and returns new values.

func (App) Serve

func (a App) Serve(msg string, options ...ExecOption) (ok bool)

Serve serves an application lives under path with options where msg describes the execution from the serving action. unless calling with Must(), Serve() will not exit test runtime on failure.

func (*App) SetConfigPath

func (a *App) SetConfigPath(path string)

func (App) Simulate

func (a App) Simulate(numBlocks, blockSize int)

Simulate runs the simulation test for the app

func (App) SourcePath

func (a App) SourcePath() string

func (App) UseRandomHomeDir

func (a App) UseRandomHomeDir() (homeDirPath string)

UseRandomHomeDir sets in the blockchain config files generated temporary directories for home directories Returns the random home directory

type AppOption

type AppOption func(*App)

func AppConfigPath

func AppConfigPath(path string) AppOption

func AppHomePath

func AppHomePath(path string) AppOption

type Env

type Env struct {
	// contains filtered or unexported fields
}

Env provides an isolated testing environment and what's needed to make it possible.

func New
