The Test Framework provides a means by which test classes can display internal information in a textual format. This mechanism works in two ways:
class IMyTest: public ITest {
...
protected:
void print(ITieredTextBuffer&);
private:
double fImportantValue; // This is important and should be shown
};
void IMyTest::print(ITieredTextBuffer& out)
{
ITest::print(out); // First show base class information
out << "tmytest important value=" << fImportantValue << '\n';
// Always end with a '\n'.
}
The content of the print function is printed only when you set the echo tier level equal to or below ITieredTextBuffer::kDetail (you set it through the command line). Remember that the default echo tier level is ITieredTextBuffer::kNormal.
mytest -t IMyTest -e dTest IMyTest (PASS) // sets echo tier level
{ run count: 1
info: {}
input: {}
TMyTest important value=100
}
If you don't include the -e option, you will see this
mytest -t IMyTest
Test IMyTest (PASS) {}
