 rest for later (test dependencies, ...). But Maven needs to know that it shouldn't try to run tests now. This can be achieved by passing `-f` option to `%mvn_build` macro.  Maven
 will stop complaining about missing test scoped dependencies from now on.
 
+[TIP]
+======
+Another major reason to disable test is to speed up the local build process.
+For this purpose it is also possible to disable the test phase by specifying an
+additional switch `--without=tests` to the `fedpkg` or the `mock` tool instead
+of adding a switch to `%mvn_build`.
+
+Another switch `--without=javadoc` causes the build to skip Javadoc generation.
+
+Note that to actually build the package with tests disabled you have to specify
+the switch to `%mvn_build`.

 [NOTE]
 ======
 It is always recommended to run all available test suites during build. It greatly improves quality of the package.
