object SUnit extends AnyRef

Unit testing methods in the spirit of JUnit framework.

Use these classes like this:

import scala.testing.SUnit
import SUnit._

class MyTest(n: String) extends TestCase(n) {

override def runTest() = n match { case "myTest1" => assertTrue(true) case "myTest2" => assertTrue("hello", false) } }

val r = new TestResult() for (tf <- r.failures()) { println(tf.toString()) }

The trait TestConsoleMain contains this code as a main method, for convenience.


  1. AnyRef
  2. Any

Type Members

  1. trait Assert extends AnyRef

    this class defines useful assert methods

  2. class AssertFailed(msg: String, stackTrace: Boolean) extends RuntimeException with Product

    an AssertFailed is thrown for a failed assertion

  3. trait Test extends AnyRef

    a Test can be run with its result being collected

  4. class TestCase extends Test with Assert

    The class TestCase defines the fixture to run multiple tests

  5. trait TestConsoleMain extends AnyRef

    Convenience trait, mix it in a TestMain object and implement "suite" to get this code

  6. class TestFailure extends AnyRef

    The class TestFailure collects a failed test together with the thrown exception

  7. class TestResult extends AnyRef

    a TestResult collects the result of executing a test case

  8. class TestSuite extends Test

    The class TestSuite runs a composite of test cases

Value Members

  1. def equals(arg0: Any): Boolean

    This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence

    This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.

    The default implementations of this method is an equivalence relation:

    • It is reflexive: for any instance x of type Any, x.equals(x) should return true.
    • It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true.
    • It is transitive: for any instances x, y, and z of type AnyRef if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

    If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is often necessary to override hashCode to ensure that objects that are "equal" (o1.equals(o2) returns true) hash to the same Int (o1.hashCode.equals(o2.hashCode)).


    the object to compare against this object for equality.


    true if the receiver object is equivalent to the argument; false otherwise.

  2. def hashCode(): Int

    Returns a hash code value for the object

    Returns a hash code value for the object.

    The default hashing algorithm is platform dependent.

    Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

  3. def toString(): String

    Returns a string representation of the object

    Returns a string representation of the object.

    The default representation is platform dependent.
