How to prioritize tests in scala? - scala

Question

I am using scalatest's FunSuite to run my tests. I want to define 2 separate test classes that have a few tests in common, so I created a BaseTest class which I extended in MainTest1 and MainTest2, in which I define additional specific tests (see code snippets below). I want the tests in MainTest1 and MainTest2 to execute in a specific order, e.g. test 4, 2, 1 and then 3. How do I achieve this?
class BaseTest extends FunSuite with BeforeAndAfter{
test("Check Content of file){
//code to check content of a file
}
test("File is not empty"){
//code to check file is not empty
}
test("Check a particular word in file"){
//code to check particular word in file
}
}
class MainTest1 extends BaseTest{
test("Check create file"){
//code to check file creation
}
}
class MainTest2 extends BaseTest{
test("Check download file"){
//code to check file downloaded properly
}
}

You can define your tests as methods and call them in the order you see fit from the children classes.
trait BaseTest extends FunSuite {
protected def test1(): Unit = test("This is test 1") { ... }
protected def test2(): Unit = test("This is test 1") { ... }
}
class MainTest1 extends BaseTest {
// Arrange these is any order you see fit
test3()
test2()
test1()
protected def test3(): Unit = test("This is a test specific to MainTest1") { ... }
}
class MainTest2 extends BaseTest {
// Arrange these is any order you see fit
test2()
test3()
test1()
protected def test3(): Unit = test("This is a test specific to MainTest2") { ... }
}
