Function initInSteps

integration/client/container_fuzz_test.go:89–121

initInSteps() performs initialization in several steps The reason for spreading the initialization out in multiple steps is that each fuzz iteration can maximum take 25 seconds when running through OSS-fuzz. Should an iteration exceed that, then the fuzzer stops.

(t *testing.T)

// take 25 seconds when running through OSS-fuzz.
// Should an iteration exceed that, then the fuzzer stops.
