The article provides a step-by-step guide for reading a text file within a Scala test class using the scalatest framework. It outlines necessary setup, including the creation of a text file named 'testfile.txt' in the 'src/test/resources' directory. The guide demonstrates how to use the scala.io package, with methods like Source.fromResource, Source.fromURL, and Source.fromFile to access the file. It emphasizes reading the file's contents using mkString, and the importance of importing scalatest to run the tests effectively.
To read the file, we can use Source.fromResource, Source.fromURL or Source.fromFile, depending on what the input will be.
Now, we will create tests to read the string in the file. First, let's import scalatest to the build.sbt of your project.
val fileSource: BufferedSource = Source.fromResource(fileName) val actualText: String = fileSource.mkString
Create a text file, let's say testfile.txt, add a text like, "I want to read this in test.", and put it to the src/test/resources folder.
