 <p>Another crucial aspect in the programming journey is knowing how to write tests. In bigger projects, usually there are separate engineers (often in much larger number than code developers) to test the code. Even in those cases, writing a few sanity test cases yourself can help you develop faster knowing that the changes aren't breaking basic functionality.</p>
 <p>There's no single consensus on test methodologies. There is <a href="https://en.wikipedia.org/wiki/Unit_testing">Unit testing</a>, <a href="https://en.wikipedia.org/wiki/Integration_testing">Integration testing</a>, <a href="https://en.wikipedia.org/wiki/Test-driven_development">Test-driven development</a> and so on. Often, a combination of these is used. These days, machine learning is also being considered to reduce the testing time, see <a href="https://hacks.mozilla.org/2020/07/testing-firefox-more-efficiently-with-machine-learning/">Testing Firefox more efficiently with machine learning</a> for example.</p>
 <p>When I start a project, I usually try to write the programs incrementally. Say I need to iterate over files from a directory. I will make sure that portion is working (usually with <code>print</code> statements), then add another feature — say file reading and test that and so on. This reduces the burden of testing a large program at once at the end. And depending upon the nature of the program, I'll add a few sanity tests at the end. For example, for my <a href="https://github.com/learnbyexample/command_help">command_help</a> project, I copy pasted a few test runs of the program with different options and arguments into a separate file and wrote a program to perform these tests programmatically whenever the source code is modified.</p>
