Tests are great, provided they actually test something. But are your tests too optimistic (assuming the code already works), or too persnickety (testing the irrelevant)?

Fixing a fuzzed-up function: Go fuzz testing explained
In the thrilling conclusion to our fuzz testing series, we’ll use Go’s fuzzer to find a real bug in our code, and also to verify the fix.
Target acquired: fuzz targets in Go tests
Let’s continue our exploration of fuzz testing in Go with a look at how to write a fuzz target for a (nearly) realistic function. This time we’ll try to detect a common kind of bug involving a confusion between runes and bytes.
What the fuzz? Introducing fuzz testing in Go
Fuzz testing is Go’s clever way of generating new test inputs that you didn’t think of—and that may flush out some hidden bugs. Stand by for things to get a little fuzzy!
Random and property-based testing in Go
Choosing good test cases for our Go programs can be a bit hit-and-miss. What if we could automate that process? Let’s talk about randomisation, property-based testing, and Go’s built-in fuzz testing feature.
