Namespaces

As this library is part of a large framework, it’s nesting of namespaces may look unnecessary complicated. If using in context of larger applications, these additional levels of namespaces provide flexibility and prevent naming conflicts.

The Erbsland Unittest interface is placed in the namespace erbsland::unittest:

namespace erbsland

namespace unittest

Shortcuts

To simplify your code, a shortcut for the base namespace is automatically created by default.

namespace el = erbsland;

We recommended that you use either use this shortcut to name the types from the library, or write using statements, importing the types you use into the namespace of your application.

Using the namespace shortcut el to use the UnitTest class.

#include <erbsland/unittest/UnitTest.hpp>

class ExampleTest : public el::UnitTest {
    // ...
}

Importing the UnitTest class, with the using statement.

#include <erbsland/unittest/UnitTest.hpp>

using el::UnitTest; // or using erbsland::UnitTest

class ExampleTest : public UnitTest {
    // ...
}

Prevent or Redefine the Shortcuts

As the shortcuts can conflict with existing codes, there are several macro definitions that allow you to disable the shortcuts or redefine them. You will have to set these definition on the compile level for the whole project.

ERBSLAND_NO_SHORT_NAMESPACE: If you set this preprocessor directive, no namespace shortcuts are created by default. You have to set this directive on the compile level for the whole project.

ERBSLAND_SHORT_NAMESPACE: Set this preprocessor directive to overwrite the name that is used for the shortcut for the erbsland namespace. You have to set this directive on the compile level for the whole project.
