Functions

func ApplyMockIO

func ApplyMockIO(c *cobra.Command) (BufferReader, BufferWriter)

ApplyMockIO replaces stdin/out/err with buffers that can be used during testing. Returns an input BufferReader and an output BufferWriter.

func DefaultContext

func DefaultContext(key storetypes.StoreKey, tkey storetypes.StoreKey) sdk.Context

DefaultContext creates a sdk.Context with a fresh MemDB that can be used in tests.

func GenerateCoinKey

func GenerateCoinKey(algo keyring.SignatureAlgo, cdc codec.Codec) (sdk.AccAddress, string, error)

GenerateCoinKey generates a new key mnemonic along with its addrress.

func GenerateSaveCoinKey

func GenerateSaveCoinKey(
	keybase keyring.Keyring,
	keyName, mnemonic string,
	overwrite bool,
	algo keyring.SignatureAlgo,
) (sdk.AccAddress, string, error)

GenerateSaveCoinKey generates a new key mnemonic with its addrress. If mnemonic is provided then it's used for key generation. The key is saved in the keyring. The function returns error if overwrite=true and the key already exists.

func GetRequestWithHeaders

func GetRequestWithHeaders(url string, headers map[string]string) ([]byte, error)

GetRequestWithHeaders defines a wrapper around an HTTP GET request with a provided URL and custom headers An error is returned if the request or reading the body fails.

func TempFile

func TempFile(t testing.TB) *os.File

TempFile returns a writable temporary file for the test to use.

func WriteToNewTempFile

func WriteToNewTempFile(t testing.TB, s string) *os.File

Write the given string to a new temporary file. Returns an open file for the test to use.

Types

type BufferReader

type BufferReader interface {
	io.Reader
	Reset(string)
}

BufferReader is implemented by types that read from a string buffer.

func ApplyMockIODiscardOutErr

func ApplyMockIODiscardOutErr(c *cobra.Command) BufferReader

ApplyMockIODiscardOutputs replaces a cobra.Command output and error streams with a dummy io.Writer. Replaces and returns the io.Reader associated to the cobra.Command input stream.

type BufferWriter

type BufferWriter interface {
	io.Writer
	Reset()
	Bytes() []byte
	String() string
}

BufferWriter is implemented by types that write to a buffer.
