Method ExpectPattern

tests/conn.go:130–147

ExpectPattern reads a line from the connection socket and checks whether is matches the supplied shell pattern (as defined by path.Match). The original line is returned.

(pat string)

// matches the supplied shell pattern (as defined by path.Match). The original
// line is returned.
func (c *Conn) ExpectPattern(pat string) string {
	c.T.Helper()

	line, err := c.Readln()
	if err != nil {
		c.T.Fatal("Unexpected I/O error:", err)
	}

	match, err := path.Match(pat, line)
	if err != nil {
		c.T.Fatal("Malformed pattern:", err)
	}
	if !match {
		c.T.Fatalf("Response line not matching the expected pattern, want %q", pat)
	}

	return line
}
