We need to create a new class of tests in dart/test/testing or something like
that so that these tests are run when using the current python script.

You should not need to call toString when giving something to print.

[Mads Ager (google), 2011/10/26 12:37:47]

Just remove the print? However, you should verify that the AST that you get here
is as you expect using Expect calls.

+    Tokenizer tokenizer = new Tokenizer(
+        @"($arch == dartc || $arch == chromium) && $mode == release");
+    tokenizer.tokenize();
+    Expect.listEquals(tokenizer.tokens,
+        ["(", "\$", "arch", "==", "dartc", "||", "\$", "arch", "==", "chromium",
+         ")", "&&", "\$", "mode", "==", "release"]);

[Mads Ager (google), 2011/10/26 12:37:47]

Parse and verify as well?

+      
+  static void test_3() {

[Mads Ager (google), 2011/10/26 12:37:47]

Use Expect calls so this test can be run by the test scripts and fail.

+    Tokenizer tokenizer = new Tokenizer(
+        @" $mode == debug && ($arch == chromium || *$arch == dartc) ");
+    try {
+      tokenizer.tokenize();
+    } catch (Exception e) {
+      print(e.toString());
+    }
+  }
+
+  static void test_4() {

[Mads Ager (google), 2011/10/26 12:37:47]

Ditto.

+    Tokenizer tokenizer = new Tokenizer(
+        @"($arch == (-dartc || $arch == chromium) && $mode == release");
+    try {
+      tokenizer.tokenize();
+    } catch (Exception e) {
+      print(e.toString());
+    }
+  }
+
+  static void test_5() {
+    Tokenizer tokenizer = new Tokenizer(
+        @"Skip , Pass if $arch == dartc, (Fail || Timeout) if " +
+        @"$arch == chromium && $mode == release");
+    tokenizer.tokenize();
+    ExpressionParser parser =
+        new ExpressionParser(new Scanner(tokenizer.tokens));
+    SetExpression ast = parser.parseSetExpression();
+    print(ast.toString());

[Mads Ager (google), 2011/10/26 12:37:47]

Verify the AST with Expect calls.
