Function methodCaller

Call a method using the right data provders

void methodCaller(alias T, U) (
  U func
);

Example

methodCaller should call the method with random numeric values 

class TestClass
{
  static int usedIntValue = 0;
  static ulong usedUlongValue = 0;

  void randomMethod(int value, ulong other)
  {
    usedIntValue = value;
    usedUlongValue = other;
  }
}

auto instance = new TestClass;

methodCaller!(instance.randomMethod)(&instance.randomMethod);

TestClass.usedIntValue.should.not.equal(0);
TestClass.usedUlongValue.should.not.equal(0);

Example

methodCaller should call the method with custom random generators 

class TestClass
{
  static int usedIntValue = 0;
  static ulong usedUlongValue = 0;

  @For!("value", { return 5; }) @For!("other", { return someCustomFunction(); }) void randomMethod(int value,
      ulong other)
  {
    usedIntValue = value;
    usedUlongValue = other;
  }
}

auto instance = new TestClass;

methodCaller!(instance.randomMethod)(&instance.randomMethod);

TestClass.usedIntValue.should.equal(5);
TestClass.usedUlongValue.should.equal(6);

Example

discoverTestCases should find the same tests like testCases 

auto discovery = new TestClassDiscovery;
discovery.addModule!(__FILE__, `trial.discovery.testclass`);

discovery
  .discoverTestCases(__FILE__)
  .map!(a => a.toString)
  .join("\n")
  .should.equal(
    discovery.getTestCases
    .sort!((a, b) => a.location.line < b.location.line)
    .map!(a => a.toString)
    .join("\n"));
