Inherited a test suite but don't want to execute its tests

[SD]

I have the following class hierarchy:

class A: public CxxTest::TestSuite

{

     _prerequisitefunc();

public:

     testA() { _prerequisite(); doTestAStuff(); }

};

class B: public A

{

public:

    testB() { _prerequisite(); doTestBStuff(); }

};

1. Is this allowed - in terms of test suite B inheriting from A?

2. When I invoke test suite B, would it execute testA()  as well?

3. If answer to 2 is yes, then does it follow an order of executing testA() before testB()?

4. I don't want testA() to be executed when test suite B is invoked. Can I inherit from A in the protected/private mode so that testA() is protected/private in class B? Would that prevent testA() from being discovered as part of test suite B?

Thanks!

P.S. For anyone interested in more context -

I have two tests - testA and testB that both have a common code, which is abstracted in the _prerequisite function. I can't put both testA and testB under the same test suite because I need testA to be always performed before testB (testA changes state in the sys environment that's needed for testB - can't mock it). I want to be able to leverage the common code while also running these two tests independently.
