+/**
+ * IntelliJ code provides a lot of statical bindings to the interested pieces of data. For example we need to execute code
+ * like below to get list of modules for the target project:
+ * <pre>
+ *   ModuleManager.getInstance(project).getModules()
+ * </pre>
+ * That means that it's not possible to test target classes in isolation if corresponding infrastructure is not set up.
+ * However, we don't want to set it up if we execute a simple standalone test.
+ * <p/>
+ * This interface is intended to encapsulate access to the underlying IntelliJ functionality.
+ * <p/>
+ * Implementations of this interface are expected to be thread-safe.
