About
Overview
In this lesson, we take a look at @ParameterizedTest
data generated from comma-separated values (CSV). There are two source annotations to help with this integration: @CsvSource
allows you to specify the values right in the annotation, in a well-arranged structure. @CsvFileSource
expects a path to a resource file, which is read in at runtime, and should contain the desired input values. This makes it possible to store test data outside of the source code itself!
Summary
- CSV data can be inlined with
@CsvSource
, ... - ...or read in from a resource file with
@CsvFileSource
