+- AssumeThatInsteadOfReturn
+
+  Tries to detect bogus uses of return statements in test methods and replaces them by ```assumeThat()``` calls.
+  
+  Novices will use these to skip test execution by bailing out early on some preconditions not met.
+  However, this suggests that the test has actually been run and passed instead of showing the test
+  as being skipped.
+
+  Return statements in ```if``` statements in main test methods (must be annotated with JUnit 4 or 
+  Jupiter @Test annotations) will be verified to have at least one ```assertThat()``` statement in the code flow.
+  Method calls within the same class will be examined for ```assertThat()``` statements, too.
+  However, at most 50 statements and down to five recursions will be tolerated before giving up.
+  
+  Currently, the quickfix may lose some comments during operation. The other branch of the ```if``` statement
+  will be inlined (blocks with declarations will remain a code block due to variable scope).
+  
+  The generated ```assumeThat()``` statement could be optimized further (similar to ```assertThat()```).
+
+  Example:
+  
+  ```
+      @Test
+      public void check_fuel_emission() {
+          if (System.getProperty("manufacturer").equals("Volkswagen")) {
+              return;
+          }
+          double nitroxppm = doWltpDrivingCycle();
+          assertThat(nitroxppm).isLessThan(500.0);
+      }
+  ```
+  will be transformed to
+  ```
+      @Test
+      public void check_fuel_emission() {
+          assumeThat(System.getProperty("manufacturer").equals("Volkswagen")).isFalse();
+          double nitroxppm = doWltpDrivingCycle();
+          assertThat(nitroxppm).isLessThan(500.0);
+      }
+  ```
+
 - JUnitAssertToAssertJ
+
+  Tries to convert most of the JUnit 4 assertions to AssertJ format.
+
+  Does not support Hamcrest-Matchers.
+  If you need that kind of conversion, you might want to check out the
+  [Assertions2AssertJ plugin](https://plugins.jetbrains.com/plugin/10345-assertions2assertj) by Ric Emery.

+Tries to detect bogus uses of return statements in test methods and replaces them by assumeThat() calls.
+<!-- tooltip end -->
+<br>
+Novices will use these to skip test execution by bailing out early on some preconditions not met.
+However, this suggests that the test has actually been run and passed instead of showing the test
+as being skipped.
+<p>Return statements in if statements in main test methods
+    (must be annotated with JUnit 4 or Jupiter @Test annotations)
+    will be verified to have at least one assertThat() statement in the code flow.
+    Method calls within the same class will be examined for assertThat() statements, too.
+    However, at most 50 statements and down to five recursions will be tolerated before giving up.
+</p>
+<p>Currently, the quickfix may lose some comments during operation. The other branch of the if statement
+    will be inlined (blocks with declarations will remain a code block due to variable scope).</p>
