Types

type Client

type Client struct {
	// Conn is the gRPC connection. Use this to create gRPC service stubs.
	Conn *grpc.ClientConn
	// contains filtered or unexported fields
}

Client owns a gRPC connection to the DUT for remote tests to use.

func Dial

func Dial(ctx context.Context, d *dut.DUT, h *testing.RPCHint) (*Client, error)

Dial establishes a gRPC connection to the test bundle executable using d and h.

The context passed in must remain valid for as long as the gRPC connection. I.e. Don't use the context from within a testing.Poll function.

Example:

cl, err := rpc.Dial(ctx, d, s.RPCHint())
if err != nil {
	return err
}
defer cl.Close(ctx)

fs := base.NewFileSystemClient(cl.Conn)

res, err := fs.ReadDir(ctx, &base.ReadDirRequest{Dir: "/mnt/stateful_partition"})
if err != nil {
	return err
}

func (*Client) Close

func (c *Client) Close(ctx context.Context, opts ...ssh.RunOption) error

Close closes the connection. TODO(b/3042409): Remove ctx param from this method.
