/**
|
|
63 |
* Wrapper around a <code>Throwable</code> object. Whenever an exception occurs
|
|
64 |
* in a test case executed on the server side, the text of this exception
|
|
65 |
* along with the stack trace as a String are sent back in the HTTP response.
|
|
66 |
* This is because some exceptions are not serializable and because the stack
|
|
67 |
* trace is implemented as a <code>transient</code> variable by the JDK so it
|
|
68 |
* cannot be transported in the response. However, we need to send a real
|
|
69 |
* exception object to JUnit so that the exception stack trace will be printed
|
|
70 |
* in the JUnit console. This class does this by being a <code>Throwable</code>
|
|
71 |
* and overloading the <code>printStackTrace()</code> methods to print a
|
|
72 |
* text stack trace.
