MergeOutgoingMetadata merges provided metadata-s and returns context with resulting value.

func MustClose 

func MustClose(tb testing.TB, closer io.Closer)

MustClose calls Close() on the Closer and fails the test in case it returns an error. This function is useful when closing via `defer`, as a simple `defer require.NoError(t, closer.Close())` would cause `closer.Close()` to be executed early already.

func MustReadFile

NewDiscardingLogEntry creates a logrus entry that discards everything.

func NewDiscardingLogger 

func NewDiscardingLogger(tb testing.TB) *logrus.Logger

NewDiscardingLogger creates a logger that discards everything.

func NewGitalyServerLogger added in v15.6.0 

func NewGitalyServerLogger(tb testing.TB) *logrus.Logger

NewGitalyServerLogger creates a logger for Gitaly servers started by current test. The logger writes logs to gitaly_server.log inside log dir from TEST_LOG_DIR env.

func NewHealthServerWithListener 

func NewHealthServerWithListener(tb testing.TB, listener net.Listener) *health.Server

NewHealthServerWithListener creates a new gRPC server with the health server set up. It will listen on the given listener.

func NewServerWithHealth 

func NewServerWithHealth(tb testing.TB, socketName string) *health.Server

NewServerWithHealth creates a new gRPC server with the health server set up. It will listen on the socket identified by `socketName`.

func ProtoEqual 

func ProtoEqual(tb testing.TB, expected, actual interface{})

ProtoEqual asserts that expected and actual protobuf messages are equal. It can accept not only proto.Message, but slices, maps, and structs too. This is required as comparing messages directly with `require.Equal` doesn't work.

func RequireDirectoryState added in v15.10.0 

func RequireDirectoryState(tb testing.TB, rootDirectory, relativeDirectory string, expected DirectoryState)

RequireDirectoryState asserts that given directory matches the expected state. The rootDirectory and relativeDirectory are joined together to decide the directory to walk. rootDirectory is trimmed out of the paths in the DirectoryState to make assertions easier by using the relative paths only. For example, given `/root-path` and `relative/path`, the directory walked is `/root-path/relative/path`. The paths in DirectoryState trim the root prefix, thus they should be like `/relative/path/...`. The beginning point of the walk has path "/".

func RequireGrpcCode 

func RequireGrpcCode(tb testing.TB, err error, expectedCode codes.Code)

RequireGrpcCode asserts that the error has the expected gRPC status code.

func RequireGrpcError 

func RequireGrpcError(tb testing.TB, expected, actual error)

RequireGrpcError asserts that expected and actual gRPC errors are equal. Comparing gRPC errors directly with `require.Equal()` will not typically work correct.

func Run 

func Run(m *testing.M, opts ...RunOption)

Run sets up required testing state and executes the given test suite. It can optionally receive a variable number of RunOptions.

func SetCtxGrpcMethod 

func SetCtxGrpcMethod(ctx context.Context, method string) context.Context

SetCtxGrpcMethod will set the gRPC context value for the proper key responsible for an RPC full method name. This directly corresponds to the gRPC function responsible for extracting the method: https://godoc.org/google.golang.org/grpc#Method

func SkipQuarantinedTest added in v15.9.0 

func SkipQuarantinedTest(t *testing.T, issue string, tests ...string)

SkipQuarantinedTest skips the test if the test name has been specified as quarantined. If no test names are provided the test is always skipped.

func SkipWithPraefect 

func SkipWithPraefect(tb testing.TB, reason string)

SkipWithPraefect skips the test if it is being executed with Praefect in front of the Gitaly.

func TempDir 

func TempDir(tb testing.TB) string

TempDir is a wrapper around os.MkdirTemp that provides a cleanup function.

func Unsetenv added in v15.2.0 

func Unsetenv(tb testing.TB, key string)

Unsetenv unsets an environment variable. The variable will be restored after the test has finished.

func WriteExecutable 

func WriteExecutable(tb testing.TB, path string, content []byte) string

WriteExecutable ensures that the parent directory exists, and writes an executable with provided content. The executable must not exist previous to writing it. Returns the path of the written executable.
