Function TestToHTTPHeader_WithTimeValue_909

pkg/util_test.go:863–883

TestToHTTPHeader_WithTimeValue_909 verifies that the ToHTTPHeader function correctly converts a map of strings to an http.Header object. It specifically checks that header values recognized as timestamps are not split by commas, while other comma-separated values are correctly split into slices.

(t *testing.T)

// header values recognized as timestamps are not split by commas, while other
// comma-separated values are correctly split into slices.
func TestToHTTPHeader_WithTimeValue_909(t *testing.T) {
	// Arrange
	mockHeader := map[string]string{
		"Date":            "Tue, 17 Jan 2023 16:34:58 IST",
		"X-Custom-Header": "value1,value2",
		"Content-Type":    "application/json",
	}

	// Act
	httpHeader := ToHTTPHeader(mockHeader)

	// Assert: every YAML key replays as exactly one wire header. The
	// recorded value is kept intact (commas included) so axios-style
	// `Accept: a, b, c` does not fan out into three duplicate-name
	// wire headers — see ToHTTPHeader's comment for why fan-out
	// breaks `dict(**request.headers)`-style server middlewares.
	require.NotNil(t, httpHeader)
	assert.Equal(t, []string{"Tue, 17 Jan 2023 16:34:58 IST"}, httpHeader["Date"])
	assert.Equal(t, []string{"value1,value2"}, httpHeader["X-Custom-Header"])
	assert.Equal(t, []string{"application/json"}, httpHeader["Content-Type"])
}

// TestToHTTPHeader_AcceptListValue_FoldedSingleHeader pins the wire
// behaviour that the duplicate-Accept TypeError fix depends on: an
