}

Input defines the content of the http request object used to execute the test case Input is built up typically from the openapi/swagger definition of the method/endpoint for a particular specification. Additional properties/fields/headers can be added or change in order to setup the http request object of the specific test case. Once setup correctly,the testcase gives the http request object to the parent Rule which determine how to execute the requestion object. On execution an http response object is received and passed back to the testcase for validation using the Expects object.

}

Match defines various types of response payload pattern and field checking. Match forms the basis for response validation outside of basic swagger/openapi schema validation Match is also used as the basis for field extraction and replacement which enable parameter passing between tests via the context. Match encapsulates a conditional statement that must 'match' in order to succeed. Matches can - - match a specified header field value for exact match - match a specified header field value using a regular expression - check that a specified header field exists in the response - check that a response body matches a regular expression - check that a response body has a particular json field present using json matching - check that a response body has a specific number of specified json array fields - check that a response body has a specific value of a specified json field - check that a response body has a specific json field and that the specific json field matches a regular expression - check that a response body is a specified length - allow for replacement of endpoint text ... e.g. {AccountId} - Authorization: allow for manipulation of Bearer tokens in http headers - Result: allow for capturing of match values for further processing - like putting into a context

TestCase defines a test that will be run and needs to be passed as part of the conformance suite in order to determine implementation conformance to a specification. Testcase have three major sections Input: 

Defines the inputs that are required by the testcase. This effectively involves preparing the http request object

Context: 

Provides a link between Discovery information and the testcase

Expects: 

Examines the http response to the testcase Input in order to determine if the expected conditions existing in the response
and therefore the testcase has passed

func LoadTestCaseFromJSONFile added in v1.1.0 

func LoadTestCaseFromJSONFile(filename string) (TestCase, error)

func (*TestCase) ApplyContext 

func (t *TestCase) ApplyContext(rulectx *Context)

ApplyContext - at the end of ApplyInputs on the testcase - we have an initial http request object ApplyContext, applies context parameters to the http object. Context parameter typically involve variables that originated in discovery The functionality of ApplyContext will grow significantly over time.

func (*TestCase) ApplyExpects 

func (t *TestCase) ApplyExpects(res *resty.Response, rulectx *Context) (bool, []error)

ApplyExpects runs the Expects section of the testcase to evaluate if the response from the system under test passes or fails The Expects section of a testcase can contain multiple conditions that need to be met to pass a testcase When a test fails, ApplyExpects is responsible for reporting back information about the failure, why it occurred, where it occurred etc.

The ApplyExpect section is also responsible for running and contextPut clauses. contextPuts are responsible for updated context variables with values selected from the test case response contextPuts will only be executed if the ApplyExpects standards match tests pass if any of the ApplyExpects match tests fail - ApplyExpects returns false and contextPuts aren't executed

func (*TestCase) ApplyInput 

func (t *TestCase) ApplyInput(rulectx *Context) (*resty.Request, error)

ApplyInput - creates an HTTP request for this test case The reason why we're doing this is that a testcase behaves like an http object It produces an http.Request - which can be sent to a server It consumes an http.Response - which it uses to validate the response against "Expects" TestCase lifecycle: 

Create a Testcase Object
Create / retrieve the http request object
Apply context information to the request object
Rule - manages passing the request object from the testcase to an appropriate endpoint handler (like the proxy)
Rule - receives http response from endpoint and provides it back to testcase
Testcase evaluates the http response object using its 'Expects' clause
Testcase passes or fails depending on the 'Expects' outcome

func (*TestCase) Prepare 

func (t *TestCase) Prepare(ctx *Context) (*resty.Request, error)

Prepare a Testcase for execution at and endpoint, results in a standard http request that encapsulates the testcase request as defined in the test case object with any context inputs/replacements etc applied

func (*TestCase) ProcessReplacementFields 

func (t *TestCase) ProcessReplacementFields(ctx *Context, showReplacementErrors bool)

func (t *TestCase) String() string

func (*TestCase) Validate 

func (t *TestCase) Validate(resp *resty.Response, ctx *Context) (bool, []error)

Validate takes the http response that results as a consequence of sending the testcase http request to the endpoint implementation. Validate is responsible for checking the http status code and running the set of 'Matches' within the 'Expect' object, to determine if all the match conditions are met - which would mean the validation passed. The context object is passed as part of the validation as its allows the match clauses to examine the request object and 'push' response variables into the context object for use in downstream test cases which are potentially part of this testcase sequence returns true - validation successful 

false - validation unsuccessful
error - adds detail to validation failure
NOTE: Validate will only return false if a check fails - no checks = true
