本文档介绍了如何使用ScalaTest编写测试用例，通过Sbt运行所有测试用例，获取覆盖率报告，以及如何指定运行特定的测试文件。推荐使用ScalaTest3.0.3，并详细说明了各个步骤的命令行操作。覆盖报告显示在`target/scala-<scala-version>/scoverage-report`目录下，包括HTML和XML格式。

Sbt Test

Sbt Test

1 Write a test using ScalaTest

ScalaTest is recommened by the official team. In my blog, I use ScalaTest 3.0.3
Please refer to the official Scala Doc to know how to use ScalaTest to write your test cases.

2 Run all test cases

# run the command in your IDE below
sbt clean coverage test

# the above is the most recommended way to run
# if you just want to get the test results, use this command is faster
sbt test

3 Get coverage report

I highly recommend this coverage tool, please refer to sbt-coverage to install it.

# after finishing step 1 (with coverage), we can get coverage report running the command below
sbt coverageReport

# Coverage reports will be in your `target/scala-<scala-version>/scoverage-report` # directory. There are HTML and XML reports. 
# The XML is useful if you need to
# programatically use the results, or if you're writing a tool.

4 Run specific test file

# you can run specific test file as follows:
sbt "testOnly yourPakageName.yourClassName"

# eg: sbt "testOnly org.apache.spark.dolphin.configuration.defaultConfigTest"
