Mocking is a key technique when it comes to writing unit tests in pretty
much any language. Whether we’re testing networking code, code relying on
hardware sensors like the accelerometer, or code using system APIs like
location services - mocking can enable us to write tests a lot easier, and
run them faster in a more predictable way.

This week, let’s take a look at a few different situations and how mocking
can be used - or avoided - to make our tests easier to write, read and run.

Creating views in code has a lot of benefits - you get to reuse styles, create abstractions, quickly prototype components in Swift Playgrounds. However, this code can easily become messy and hard to read. It requires a certain amount of discipline to make it nice and readable. If you do, you would definitely thank yourself later when that code needs to be changed.
