Last year at Droidcon Online Xavier Gouchet gave a talk titled: “It’s time to up your test game<\/a>“. Here he talked about testing and more specifically fuzz testing.<\/p>\n\n\n\n

Wikipedia describes fuzz testing as follows:<\/p>\n\n\n\n

Fuzzing or fuzz testing is an automated software testing technique that involves providing invalid, unexpected, or random data as inputs to a computer program. The program is then monitored for exceptions such as crashes, failing built-in code assertions, or potential memory leaks.<\/p>Wikipedia<\/a><\/cite><\/blockquote>\n\n\n\n

In his talk he introduced Elmyr<\/a>: <\/p>\n\n\n\n

A Kotlin library providing tools to generate \u201crandom\u201d values. <\/p>Elmyr github page<\/cite><\/blockquote>\n\n\n\n

Seeing how easy it was to use Elmyr, it got me inspired to start using it in my own projects as well. About a month ago I found some time to get started and I’m loving it! <\/p>\n\n\n\n

Adding and using Elmyr turned out to be super easy. It took very little time to get up and running.<\/p>\n\n\n\n

What surprised me most is that almost immediately I found a bug in my code due to the random test data that Elmyr produces!<\/p>\n\n\n\n

Another thing I really like is that I no longer need to think about what test data to use with my subject under test. All I need to do is ask Elmyr to give me some random data.<\/p>\n\n\n\n

If you need Elmyr to support some of your own classes for fuzzing, simply create a new ForgeryFactory<\/code><\/a>, add it to the Forge<\/code> in your test and you’re done.<\/p>\n\n\n\n

Now I wish that I learned about fuzz testing ages ago!<\/p>\n\n\n\n

If Elmyr doesn’t do the trick for you, Github hosts tons of other fuzzing libraries<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
