This is only relevant125when running in parallel and output to stdout/stderr is being intercepted.  You generally126don't need to call this function - however there are cases when Ginkgo's output interception127mechanisms can interfere with external processes launched by the test process.128In particular, if an external process is launched that has cmd.Stdout/cmd.Stderr set to os.Stdout/os.Stderr129then Ginkgo's output interceptor will hang.  To circumvent this, set cmd.Stdout/cmd.Stderr to GinkgoWriter.130If, for some reason, you aren't able to do that, you can PauseOutputInterception() before starting the process131then ResumeOutputInterception() after starting it.132Note that PauseOutputInterception() does not cause stdout writes to print to the console -133this simply stops intercepting and storing stdout writes to an internal buffer.134*/135func PauseOutputInterception() {136	if outputInterceptor == nil {137		return138	}139	outputInterceptor.PauseIntercepting()140}141//ResumeOutputInterception() - see docs for PauseOutputInterception()142func ResumeOutputInterception() {143	if outputInterceptor == nil {144		return145	}146	outputInterceptor.ResumeIntercepting()147}148/*149RunSpecs is the entry point for the Ginkgo spec runner.150You must call this within a Golang testing TestX(t *testing.T) function.151If you bootstrapped your suite with "ginkgo bootstrap" this is already152done for you.153Ginkgo is typically configured via command-line flags.  This configuration154can be overridden, however, and passed into RunSpecs as optional arguments:155	func TestMySuite(t *testing.T)  {156		RegisterFailHandler(gomega.Fail)157		// fetch the current config158		suiteConfig, reporterConfig := GinkgoConfiguration()159		// adjust it160		suiteConfig.SkipStrings = []string{"NEVER-RUN"}161		reporterConfig.FullTrace = true162		// pass it in to RunSpecs163		RunSpecs(t, "My Suite", suiteConfig, reporterConfig)164	}165Note that some configuration changes can lead to undefined behavior.  For example,166you should not change ParallelProcess or ParallelTotal as the Ginkgo CLI is responsible167for setting these and orchestrating parallel specs across the parallel processes.  See http://onsi.github.io/ginkgo/#spec-parallelization168for more on how specs are parallelized in Ginkgo.169You can also pass suite-level Label() decorators to RunSpecs.

If you call Fail, or make an assertion, within a goroutine launched by your spec you must269add defer GinkgoRecover() to the goroutine to catch the panic emitted by Fail.270You can call Fail in any Setup or Subject node closure.271You can learn more about how Ginkgo manages failures here: https://onsi.github.io/ginkgo/#mental-model-how-ginkgo-handles-failure272*/273func Fail(message string, callerSkip ...int) {274	skip := 0275	if len(callerSkip) > 0 {276		skip = callerSkip[0]277	}278	cl := types.NewCodeLocationWithStackTrace(skip + 1)279	global.Failer.Fail(message, cl)280	panic(types.GinkgoErrors.UncaughtGinkgoPanic(cl))281}282/*283AbortSuite instructs Ginkgo to fail the current spec and skip all subsequent specs, thereby aborting the suite.284You can call AbortSuite in any Setup or Subject node closure.285You can learn more about how Ginkgo handles suite interruptions here: https://onsi.github.io/ginkgo/#interrupting-aborting-and-timing-out-suites286*/287func AbortSuite(message string, callerSkip ...int) {288	skip := 0289	if len(callerSkip) > 0 {290		skip = callerSkip[0]291	}292	cl := types.NewCodeLocationWithStackTrace(skip + 1)293	global.Failer.AbortSuite(message, cl)294	panic(types.GinkgoErrors.UncaughtGinkgoPanic(cl))295}296/*297GinkgoRecover should be deferred at the top of any spawned goroutine that (may) call `Fail`298Since Gomega assertions call fail, you should throw a `defer GinkgoRecover()` at the top of any goroutine that299calls out to Gomega300Here's why: Ginkgo's `Fail` method records the failure and then panics to prevent301further assertions from running.  This panic must be recovered.  Normally, Ginkgo recovers the panic for you,302however if a panic originates on a goroutine *launched* from one of your specs there's no303way for Ginkgo to rescue the panic.
