Usage

An executable example is in example/main.go.

• Status Code

err := isugata.Validate(res,
  isugata.WithStatusCode(http.StatusOK),
)

• Content Type

err := isugata.Validate(res,
  isugata.WithContentType("application/json"),
)

• JSON Body Validation

type user struct {
 ID   int    `json:"id"`
 Name string `json:"name"`
}

err := isugata.Validate(res,
  isugata.WithJSONValidation[user](
    isugata.JSONEquals[user](
      user{
        ID:   1,
        Name: "test",
      },
    ),
  ),
)

• JSON Array Body Validation

type user struct {
 ID   int    `json:"id"`
 Name string `json:"name"`
}

err := isugata.Validate(res,
  isugata.WithJSONArrayValidation[user](
    isugata.JSONArrayLengthEquals[user](2),
    isugata.JSONArrayValidateOrder[user, int](
      func(u user) int { return u.ID },
      isugata.Asc,
    ),
    isugata.JSONArrayValidateEach[user](
      func(body user) error {
        if body.Name != fmt.Sprintf("test%d", body.ID) {
          return fmt.Errorf("expected: test%d, actual: %s", body.ID, body.Name)
        }
        return nil
