Things That Go Boom
It is easier to make a safe light bulb than to make a safe explosive.
Abstractions For Binary Search, Part 10: Putting It All Together
After the discussions of the last few weeks, we are finally ready to build our test cases.
The Touch of a Button
Of course, I wasn't satisfied with the simple approach, so I added a bit of code to sense swipes much as you would find on a touchscreen phone.
Abstractions For Binary Search, Part 9: What Do We Need to Test?
Many people confuse the idea of a test case working correctly with the idea of a program producing correct output.
Abstractions for Binary Search, Part 8: What Does It Mean To Say "It Works?"
Last week, we talked in general terms about how to test a binary-search function. Now let's get specific.
