C++TESK Testing ToolKit

h1. C++TESK Cookbook

h2. Developing a Report Printer

If you want to change the way the tool describes failures (you don’t like the printing style or you get used to work with a different format or you need to integrate your test system with a bug tracker or whatever), the best solution is probably to write your own report printer. It can be easily done by defining one method in a printer class and registering the printer in C++TESK Report Subsystem. The steps are as follows.

h4. Step 1. Printer Definition

<pre><code class="cpp">

#include <hw/report/printer.hpp>

using namespace cpptesk::hw::report;

// You need to inherit from the base printer

structure MyPrinter: public ReportPrinter

{

    // ... and to define (override) the print method.

    virtual void print(std::ostream &out, const Report &report) { ... }

};

</code></pre>

h4. Step 2. Printer Registration

<pre><code class="cpp">

// If the printer is ready, it may be registered.

CPPTESK_MODEL(MyModel)

{

    MyModel()

    {

        // Printers are registered in a model.

        registerReportPrinter(new MyPrinter());

        ...

    }

};

</code></pre>

Before developing your report printer make sure that printer you need to develop (or a similar one) doesn’t exist in the library.
