The Psychology of Testing
2:22:02 – 2:30:00 Testing Fundamentals The three things you need to know about testing. 1: Read the code, 2: Mind your dependencies, 3: Sharpen your environmental Ax. It’s easier to do it properly than do it wrongly.
2:30:00 – 2:38:40 Write Tests First If you want to test your software, test it at the point of writing. Once it is written, it’s too late.
2:38:40 – 2:49:50 Testing Large and Small Projects Bigger projects are no harder than small projects – there is just more work. Find the stuff you actually need and then work with them. The more nested the dependencies, the harder things will become for you.
2:49:50 – 2:57:30 Testing Classes and Business Logic How do you test a class? You test it by replacing the class’s sub-dependencies with ‘friendly’ dummy modules. Then everything that goes wrong is in the class under test. The real sub-dependencies can be plugged back in later.
2:57:30 – 3:06:45 Testing Examples Testing after the fact means you assume the code works, then try it out. The problem is largely insoluble.
3:06:45 – 3:13:30 Testing code vs. Production code While simple objects can be trusted to be benign, more involved objects need careful handling. The ‘new’ operator is best avoided.
