How to read file content from classpath ?

To get a content of file from classpath, we can use the mix of getClass() and getText methods:

@Test
void "should correctly load file content from classpath"() {
  // sample_file.txt located in /test/resources directory
  String content = this.getClass().getResource('/sample_file.txt').text

  assertThat(content).isEqualTo('Sample file')
}
