Overview ¶
Package gdutils provides State struct with methods that may be used for behavioral testing of HTTP API.
State may be initialized by two ways:
First, returns *State with default services:
func NewDefaultState(isDebug bool, jsonSchemaDir string) *State
Second, more customisable returns *State with provided services:
func NewState(cli *http.Client, c cache.Cache, jv JSONSchemaValidators, r jsonpath.Resolver, d formatter.Deserializer, isDebug bool) *State
No matter which way you choose, you can inject your custom services afterwards with one of available setters:
func (s *State) SetDebugger(d debugger.Debugger) func (s *State) SetCache(c cache.Cache) func (s *State) SetHttpContext(c httpctx.HttpContext) func (s *State) SetTemplateEngine(t template.Engine) func (s *State) SetJSONSchemaValidators(j JSONSchemaValidators) func (s *State) SetJSONPathResolver(j jsonpath.Resolver) func (s *State) SetDeserializer(d formatter.Deserializer)
Those services will be used in utility methods. For example, if you want to use your own debugger, create your own struct, implement debugger.Debugger interface on it, and then inject it with "func (s *State) SetDebugger(d debugger.Debugger)" method.
Testing HTTP API usually consist the following aspects:
* Data generation:
func (s *State) IGenerateARandomIntInTheRangeToAndSaveItAs(from, to int, cacheKey string) error func (s *State) IGenerateARandomFloatInTheRangeToAndSaveItAs(from, to int, cacheKey string) error func (s *State) IGenerateARandomRunesInTheRangeToAndSaveItAs(charset string) func(from, to int, cacheKey string) error func (s *State) IGenerateARandomSentenceInTheRangeFromToWordsAndSaveItAs(charset string, wordMinLength, wordMaxLength int) func(from, to int, cacheKey string) error func (s *State) IGetTimeAndTravelByAndSaveItAs(t time.Time, timeDirection timeutils.TimeDirection, timeDuration time.Duration, cacheKey string) error func (s *State) IGenerateCurrentTimeAndTravelByAndSaveItAs(timeDirection timeutils.TimeDirection, timeDuration time.Duration, cacheKey string) error
* Sending HTTP(s) requests:
func (s *State) ISendRequestToWithBodyAndHeaders(method, urlTemplate string, bodyTemplate string) error
or
func (s *State) IPrepareNewRequestToAndSaveItAs(method, urlTemplate, cacheKey string) error func (s *State) ISetFollowingHeadersForPreparedRequest(cacheKey string, headersTemplate string) error func (s *State) ISetFollowingBodyForPreparedRequest(cacheKey string, bodyTemplate string) error func (s *State) ISendRequest(cacheKey string) error
* Assertions:
func (s *State) TheResponseStatusCodeShouldBe(code int) error func (s *State) TheResponseBodyShouldHaveFormat(dataFormat dataformat.DataFormat) error func (s *State) TheJSONResponseShouldHaveNode(expr string) error func (s *State) TheJSONNodeShouldNotBe(expr string, goType string) error func (s *State) TheJSONNodeShouldBe(expr string, goType string) error func (s *State) TheJSONResponseShouldHaveNodes(nodeExprs string) error func (s *State) TheJSONNodeShouldBeSliceOfLength(expr string, length int) error func (s *State) TheJSONNodeShouldBeOfValue(expr, dataType, dataValue string) error func (s *State) TheResponseShouldHaveHeader(name string) error func (s *State) TheResponseShouldHaveHeaderOfValue(name, value string) error func (s *State) IValidateLastResponseBodyWithSchemaReference(source string) error func (s *State) IValidateLastResponseBodyWithSchemaString(jsonSchema string) error func (s *State) TimeBetweenLastHTTPRequestResponseShouldBeLessThanOrEqualTo(timeInterval time.Duration)
* Preserving JSON nodes:
func (s *State) ISaveFromTheLastResponseJSONNodeAs(expr, cacheKey string) error func (s *State) ISaveAs(value, cacheKey string) error
* Temporary stopping scenario execution:
func (s *State) IWait(timeInterval time.Duration) error
* Debugging:
func (s *State) IPrintLastResponseBody() error func (s *State) IStartDebugMode() error func (s *State) IStopDebugMode() error
