Examples with TestingResourceValidator org.eclipse.xpect.xtext.lib.tests.ValidationTestModuleSetup.TestingResourceValidator used on opensource projects

Example 1 with TestingResourceValidator

use of org.eclipse.xpect.xtext.lib.tests.ValidationTestModuleSetup.TestingResourceValidator in project n4js by eclipse.

the class QuickFixXpectMethod method quickFix.

/**
 * Choose quick fix and apply
 *
 * @param expectation
 *            from right hand side - expected changes to code, especially cursor position.
 * @param resource
 *            injected resource under test
 * @param offset
 *            parsed arg2 offset cursor position
 * @param selected
 *            parsed arg3 - chosen quick fix to apply
 * @param mode
 *            parsed arg4 if 'fileValid' additional validation check after application
 *
 * @param specifiedResourcePath
 *            Specifies the relative path of the resource in which the quickfix applies
 *
 * @param reparseResource
 *            Specifies if the resource is reset after application of the quick fix or not.
 *
 *            Note: In case of passing false the caller has to reset the resource on its own as it is essential for
 *            the following quick fix xpect method calls.
 *
 * @throws Exception
 *             in test failure.
