Macro Definition Documentation

TEST_METHOD

#define TEST_METHOD	(		klass,
			method )

Value:

::detail::test_method<klass, &klass::method>(#klass, #method)

Run a class method as a test.

Each invocation of TEST_METHOD() constructs a new instance of 'klass' on the stack. Thus constructor and destructor can be used for common test setup and tear down.

namespace { // anon
    struct MyTest {
          MyTest() { } // setup
          ~MyTest() { } // tear down
          void test1() {}
          void test2() {}
    };
} // namespace anon
MAIN(somename) {
      testPlan(0);
      TEST_METHOD(MyTest, test1)
      TEST_METHOD(MyTest, test2)
      return testDone();
}

testEqual

#define testEqual	(		LHS,
			RHS )

Value:

::detail::testEqualx(#LHS, #RHS, LHS, RHS)

Compare equality. print left and right hand values and expression strings

int x=5;
testEqual(x, 5);
// prints "ok 1 - x (5) == 5 (5)\n"
testEqual(x, 6)<<" oops";
// prints "not ok 1 - x (5) == 6 (6) oops\n"

Definition at line 108 of file pvUnitTest.h.

testNotEqual

#define testNotEqual	(		LHS,
			RHS )

Value:

::detail::testNotEqualx(#LHS, #RHS, LHS, RHS)

Definition at line 110 of file pvUnitTest.h.

testShow

#define testShow

(

)

Value:

::detail::testPassx()

Print test output w/o testing

testShow()<<"Foo";

Definition at line 138 of file pvUnitTest.h.

testThrows

#define testThrows	(		EXC,
			CODE )

Value:

try{ CODE; testFail("unexpected success of " #CODE); }catch(EXC& e){testPass("catch expected exception: %s", e.what());}

Test that a given block throws an exception

testThrows(std::runtime_error, somefunc(5))

Definition at line 130 of file pvUnitTest.h.

testTrue

#define testTrue

(

B

)

Value:

::detail::testPassx(!!(B))<<#B

Pass/fail from boolean

bool y=true;
testTrue(y);
// prints "ok 1 - y\n"
testTrue(!y)<<" oops";
// prints "not ok 1 - !y oops\n"

testFieldEqual() [2/2]

template<typename PVD>

::detail::testPassx testFieldEqual	(	const std::tr1::shared_ptr< const epics::pvData::PVStructure > &	val,
		const char *	name,
		typename PVD::value_type	expect )

Compare value of PVStructure field

PVStructurePtr x(.....);
testFieldEqual<epics::pvData::PVInt>(x, "alarm.severity", 1);
