If you are reading this chapter, this means that the wide range of tools and
|
|
interfaces covered in the previous sections are not sufficient for the testing
|
|
scenario you have in mind. You are here to bend the <span class="emphasis"><em>Unit Test Framework</em></span>
|
|
to your will and ... we are not going to stop you. Instead we'll try to guide
|
|
you so that some dark corners do not look scary.
|
|
</p>
|
|
<p>
|
|
In most cases the <span class="emphasis"><em>Unit Test Framework</em></span> is going to be supplied
|
|
for you either as part of your system libraries or set of libraries used by
|
|
your companies. Yet if you are facing the necessity to build your own static
|
|
or dynamic library of the <span class="emphasis"><em>Unit Test Framework</em></span> or need
|
|
to customize the build for any reason, section <a class="link" href="adv_scenarios/build_utf.html" title="Building the Unit Test Framework">Building
|
|
the <span class="emphasis"><em>Unit Test Framework</em></span></a> covers all the necessary
|
|
steps.
|
|
</p>
|
|
<p>
|
|
To streamline the experience of setting up your test module, the <span class="emphasis"><em>Unit
|
|
Test Framework</em></span> provides some default initialization logic for them.
|
|
Usually the default test module initialization will work just fine, but if
|
|
you want to implement some custom initialization or change how default initialization
|
|
behaves you need to first look in <span class="bold"><strong>Test module initialization</strong></span>
|
|
section. Here you'll learn about various options the <span class="emphasis"><em>Unit Test Framework</em></span>
|
|
provides for you to customize this behavior.
|
|
</p>
|
|
<p>
|
|
The part of the framework which loads, initializes and executed your test module
|
|
is called the <span class="bold"><strong>Test Runner</strong></span>. Each usage variant
|
|
comes with default test runner. If, instead, you prefer to implement your own
|
|
entry point into the test module (for example if you need to implement the
|
|
<code class="computeroutput"><span class="identifier">main</span></code> function yourself and
|
|
not use the one provided by the <span class="emphasis"><em>Unit Test Framework</em></span>, you
|
|
need to learn about <span class="emphasis"><em>Unit Test Framework</em></span> interfaces involved
|
|
in test runners operations. These are covered in the <span class="bold"><strong>Test
|
|
runners</strong></span> section. Let me reiterate that you only need to this section
|
|
if regular regular options for customization of initialization logic like
|
|
<a class="link" href="tests_organization/fixtures.html" title="Fixtures">fixtures</a> or
|
|
<a class="link" href="tests_organization/decorators.html" title="Decorators">decorators</a>
|
|
are not sufficient for your purposes.
