public class JUnitShell
extends com.google.gwt.dev.DevMode

This class is responsible for hosting JUnit test case execution. There are three main pieces to the JUnit system.

• Test environment
• Client classes
• Server classes

The test environment consists of this class and the non-translatable version of GWTTestCase. These two classes integrate directly into the real JUnit test process.

The client classes consist of the translatable version of GWTTestCase, translatable JUnit classes, and the user's own GWTTestCase-derived class. The client communicates to the server via RPC.

The server consists of JUnitHostImpl, an RPC servlet which communicates back to the test environment through a JUnitMessageQueue, thus closing the loop.

Method Detail

getMessageQueue

public static JUnitMessageQueue getMessageQueue()

Called by JUnitHostImpl to get an interface into the test process.

Returns:

The JUnitMessageQueue interface that belongs to the singleton JUnitShell, or null if no such singleton exists.

getRemoteUserAgents

public static Set<String> getRemoteUserAgents()

Get the set of remote user agents to compile.

Returns:

the set of remote user agents

getCompilerOptions

public static com.google.gwt.dev.CompilerOptions getCompilerOptions()

Get the compiler options

Returns:

the compiler options that have been set.

mustNotExecuteTest

public static boolean mustNotExecuteTest(JUnitHost.TestInfo testInfo)

Checks if a testCase should not be executed. Currently, a test is either executed on all clients (mentioned in this test) or on no clients.

Parameters:

testInfo - the test info to check

Returns:

true iff the test should not be executed on any of the specified clients.

runTest

public static void runTest(GWTTestCase testCase,
                           TestResult testResult)
                    throws com.google.gwt.core.ext.UnableToCompleteException

Entry point for GWTTestCase. Gets or creates the singleton JUnitShell and invokes its runTestImpl(GWTTestCase, TestResult).

Throws:

com.google.gwt.core.ext.UnableToCompleteException
