Should we enable these on CI?
go test -fuzz FuzzXYZ
@AdamKorcz - Would it be covered by #7052? I don't want to maintain the list of the fuzzing tests if possible. |

In addition to oss-fuzz's CIFuzz (see containerd#7052), this commit adds a small shell script that run all fuzzing tests with go test -fuzz. While running for 30 seconds would be too short to acutally find issues, we want to make sure that these fuzzing tests are not fundamentally broken. Signed-off-by: Kazuyoshi Kato <[email protected]>

@mxpv Can you take a look again? Your comment should be addressed by the last commit. |

Why was this removed? Is it not needed for the oss-fuzz integration?

This one is moved under pkg/cap.

Yes, but the signature is now func (*testing.F) rather than func ([]byte) int and is moved into a _test.go file. Does the external OSS-fuzz runner that consumes these functions (from #4841) know how to invoke a func (*testing.F)?

Yes. Some other changes might be needed in the build script, though. For example, utilities from _test.go files are currently not available to OSS-Fuzz, so these files need to be non _test.go files.

Both can be used by OSS-Fuzz.

This one is moved under platforms/. Since Go's fuzzing support is part of testing package. I'm moving fuzzing from contrib/fuzz to each package if possible.

These two fuzzers are simple enough to use Go 1.18's testing.F
