58 * For example, if there is a test file foo_test.dart with tests 'test1'
59 * and 'test2', it will look for foo_test/test1.txt and foo_test/test2.txt
60 * for text render layout files. If these exist it will do additional checks
61 * of the rendered layout; if not, the test will fail.
57 * 62 *
58 * Here is a simple example test: 63 * Layout file (re)generation can be done using `--regenerate`. This will
59 * 64 * create or update the layout files (and implicitly pass the tests).
60 * #library('sample');
61 * #import('dart:html');
62 * #import('pkg:unittest/unittest.dart');
63 *
64 * main() {
65 * group('foo', () {
66 * test('test 1', () {
67 * document.body.nodes.add(new Element.html("<p>Test 1</p>"));
68 * });
69 * test('test 2', () {
70 * document.body.nodes.add(new Element.html("<p>Test 2</p>"));
71 * });
72 * });
73 * }
74 *
75 * And a sample matching .render file:
76 *
77 * [foo test 1]
78 * RenderBlock {P} at (0,0) size 284x20
79 * RenderText {#text} at (0,0) size 38x19
80 * text run at (0,0) width 38: "Test 1"
81 * [foo test 2]
82 * RenderBlock {P} at (0,0) size 284x20
83 * RenderText {#text} at (0,0) size 38x19
84 * text run at (0,0) width 38: "Test 2"
85 *
86 * Note that the render content is only the content inside the <body> element,
87 * not including the body element itself.
88 *
89 * Running testrunner with a `--generate-renders` flag will make it create
90 * .render files for you.
