The TempDir Function

Let’s learn about the TempDir function.

We'll cover the following...

The Cleanup() function
Coding example
Let’s try our code

The TempDir() method works with both testing and benchmarking. Its purpose is to create a temporary directory that is going to be used during testing or benchmarking. Go automatically removes that temporary directory when the test and its subtests or the benchmarks are about to finish with the help of the CleanUp() method—this is arranged by Go and we do not need to use and implement CleanUp() on our own. The exact place where the temporary directory is going to be created depends on the operating system used. On macOS, it is under /var/folders whereas on Linux it is under /tmp. We are going to illustrate TempDir() in the next section where we also talk about Cleanup().
