You could be tempted to create test cases directly from the grammar (writing a tool for that isn't that hard). But think a moment about this. What would you test then? Your unit tests would always succeed, unless you use generated test cases from an earlier version of the grammar.
A special case is when you write a grammar for a language that has already a grammar for another parser generation tool. In that case you could use the original grammar to generate test cases which you then can use to test your new grammar for conformity.
Meanwhile I got another idea that would allow for better testing: have a sentence generator that generates random sentences from your grammar (I'm currently working on one in my Visual Studio Code ANTLR4 extension). The produced sentences can then be examined using a heuristic approach, for their validity:
This would already cover a good part of the language, but has limits. Matching code and generating it are not 1:1 operations. A grammar rule that matches certain (valid) input might generate much more than that (and can so produce invalid input).
In one chapter of his book 'Software Testing Techniques' Boris Beizer addresses the topic of 'syntax testing'. The basic idea is to (mentally or actually) take a grammar and represent it as a syntax diagram (aka railroad diagram). For systematic testing, this graph then would be covered: Good cases where the input matches the elements, but also bad cases for each node. Iterations and recursive calls would be handled like loops, that is, cases with zero, one, two, one less than max, max, once above max iterations (i.e. occurrences of the respective syntactic element).
So I've been making a grammar in Eclipse with ANTLR v3.4 and I've made one that works and I want to make sure when I edit it everything still works. I can go into the interpretter everytime but that seems like a huge waste of time.
Questions:I've read about gunit but the link it gives to download gUnit:( $gunit/lastSuccessfulBuild/ ) doesn't work. How can I get gUnit.What is the best way to test grammars? Is it actually gUnit or should I just do java tests like jUnit tests?
I recently completed two ANTLR3 assignments (I'm working on my Master's in Computer Science) using Eclipse. I found no single document that had a process for installing, configuring, writing, and debugging a grammar in Eclipse. So, after working through various issues, I found the easiest thing to do was to stay in Eclipse for testing.
To use the process I have come to use (outlined below) you must first have the ANTLR IDE v2.1.2 installed. Add it right from inside Eclipse Indigo: This site also has some useful doc on using the ANTLR IDE. Once installed, the IDE has to be configured. Video tutorials are a bit out of date but helpful. See a detailed how to guide on configuring ANTLR IDE in Eclipse. The main configuration item is the java output folder. Do this in Eclipse by going to Windows, Preferences, ANTLR, Code Generator, check Project relative folder and in the Output folder name box type a folder name (mine is called "antlr-java", others use "generated").
My approach to validating grammars is to actually validate the the entire parser with "normal" unit tests. The thing is, you should have unit tests in place anyway and the tests that check for grammar regression you just add it there. The thing is in my experience that most errors come in semantic analysis and reduction and not the grammar.
The Usage and Grammar Test is a graduation requirement for all UNC Hussman majors and second majors. Students are required to score 70 percent or better on the test before graduation.
The test evaluates word usage, grammar and punctuation competencies based on AP style. It is a timed 60-minute test given electronically through Sakai that consists of 100 multiple-choice questions. Allow about one hour in your schedule for this test.
The test is offered multiple times throughout each fall and spring semester and once each summer session. There is no limit to how many times the test is taken. Seats are limited. Availability can be competitive near the end of the semester. Make every effort to fulfill this obligation before your final semester.
Current MEJO 153 students will take the test once only during class. MEJO 153 students do NOT register for seats through the calendar until the next term (if a passing score was not earned in class).
Tests are proctored via Zoom and thus require a laptop with an operable camera for completion. Mozilla Firefox is the recommended browser to use with Sakai for all operating systems. Download it to your laptop before test day. Ensure your laptop is fully charged or connected to a power source during testing.
The following test contains 50 multiple choice questions related to various fields of English grammar: tenses; modals; conditionals and unreal tenses; indirect speech; passive voice and causative structures; infinitives, gerunds and participles; relative clauses; inversion; articles; countable and uncountable nouns.

There's one challenge in coming up with such a test, however. Different books and teachers have different ideas about what constitutes correct English grammar, and there are differences of opinion even about such issues as how to define grammatical terms. That means that no substantive assessment of grammatical knowledge can be completely theory neutral. I've tried to create questions that don't depend too narrowly on a single approach to grammar, but I also won't accept any old assertion just because you can find it in some book or other. I have tried to avoid "gotcha" questions where there are significant disagreements among experts as to what should count as correct. That doesn't mean, however, that you won't be surprised by a few of the answers if you're unfamiliar with modern accounts of English grammar.
The correct answers involving grammatical terminology are those that reflect a mainstream consensus among contemporary linguists, one broadly in keeping with the major recent reference books of English grammar. Unless otherwise indicated, the term "error" is used to mean that the language in question does not conform to the requirements of standard written English, as widely understood by English teachers and editors. The questions will become harder as you move through the quiz. If you have a reasonable knowledge of traditional grammatical concepts, you should be able to get most of these right, although you will need some exposure to linguistics to get a few of the final ones.
Update 1/7/15: Now that several hundred people have taken the complete quiz, I've used the statistics to refine the quiz a bit, clarifying the wording of a few questions and replacing a couple that weren't working the way I'd hoped.
When Word finishes checking the spelling and grammar and errors corrected, you can choose to display information about the reading level of the document, including readability scores according to the Flesch-Kincaid Grade Level test and Flesch Reading Ease test. Understand readability scores.
This test rates text on a U.S. school grade level. For example, a score of 8.0 means that an eighth grader can understand the document. For most documents, aim for a score of approximately 7.0 to 8.0.

The College Composition exam uses multiple-choice questions and essays to assess writing skills taught in most first-year college composition courses. Those skills include analysis, argumentation, synthesis, usage, ability to recognize logical development, and research.
Essays are scored twice a month by college English faculty from throughout the country via an online scoring system. Each essay is scored by at least two different readers, and the scores are then combined.
This combined score is weighted equally with the score from the multiple-choice section. These scores are then combined to yield the test taker's score. The resulting combined score is reported as a single scaled score between 20 and 80. Separate scores are not reported for the multiple-choice and essay sections.
Note: Although scores are provided immediately upon completion for other CLEP exams, scores for the College Composition exam are available to test takers one to two weeks after the test date. View the complete College Composition Scoring and Score Availability Dates.
