Example 3 with RegionWithCursor

use of org.eclipse.n4js.xpect.ui.methods.contentassist.RegionWithCursor in project n4js by eclipse.

the class ProposalXpectMethod method proposalChange.

// @formatter:off
/**
 * Test the application of the given content assist entry. After applying the content assist there should be the
 * expected diff produced when comparing the document before and after applying the content assist.
 *
 * The diff has the following semantics:
 *
 * "  ": (whitespace) nothing changed
 * "+ ": line was added
 * "- ": line was deleted
 * "| ": line was modified, displayed as [oldText|newText]
 *
 * If the given expected content assist entry cannot be found, an error message is inserted at the offset resulting
 * in expectation mismatch and so also to a failing test.
 *
 * Also clf.

 *   (...)
 *  }
 * }
 * var A a = new A();
 * |a.[methodA|methodA2methodA]
 * --- *\/
 *
 * Please note, that the comparison always contains also some lines around the line that contains the diff.
 * Xpect currently doesn't allow to configure the number of those lines.
 *
 * @param expectation
 *            the expected diff comparing the document before and after applying the content assist
 * @param resource
 *            the resource under test
 * @param arg2
 *            the offset of where to invoke content assist (note: it must be named arg2 as Xpect injects the
 *            parameter values by position)
