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).

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.
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.
Colleges set their own credit-granting policies and therefore differ with regard to their acceptance of the College Composition exam. Most colleges will grant course credit for a first-year composition or English course that emphasizes expository writing; others will grant credit toward satisfying a liberal arts or distribution requirement in English.
The exam measures test takers' knowledge of the fundamental principles of rhetoric and composition and their ability to apply Standard Written English principles. In addition, the exam requires a familiarity with research and reference skills. In one of the two essays, test takers must develop a position by building an argument in which they synthesize information from two provided sources, which they must cite. The requirement that test takers cite the sources they use reflects the recognition of source attribution as an essential skill in college writing courses.
The skills assessed in the College Composition exam follow. The numbers in parentheses indicate the approximate percentages of exam questions on those topics. The bulleted lists under each topic are meant to be representative rather than prescriptive.
This section measures test takers' awareness of a variety of logical, structural, and grammatical relationships within sentences. The questions test recognition of acceptable usage relating to the items below:
This section measures test takers' familiarity with elements of the following basic reference and research skills, which are tested primarily in sets but may also be tested through stand-alone questions. In the passage-based sets, the elements listed under Revision Skills and Rhetorical Analysis may also be tested. In addition, this section will cover the following skills:
In addition to the multiple-choice section, the College Composition exam includes a mandatory essay section that tests skills of argumentation, analysis, and synthesis. This section of the exam consists of two essays, both of which measure a test taker's ability to write clearly and effectively. The first essay is based on the test taker's reading, observation, or experience, while the second requires test takers to synthesize and cite two sources that are provided. Test takers have 30 minutes to write the first essay and 40 minutes to read the two sources and write the second essay. The essays must be typed on the computer.
Write an essay in which you discuss the extent to which you agree or disagree with the statement provided. Support your discussion with specific reasons and examples from your reading, experience, or observations.

Background: Despite a large body of evidence regarding reliable indicators of language deficits in young children, there has not been a standardized, quick screen for language impairment. The Grammar and Phonology Screening (GAPS) test was therefore designed as a short, reliable assessment of young children's language abilities.
Aims: GAPS was designed to provide a quick screening test to assess whether pre- and early school entry children have the necessary grammar and pre-reading phonological skills needed for education and social development. This paper reports the theoretical background to the test, the pilot study and reliability, and the standardization.
Methods: This 10-min test comprises 11 test sentences and eight test nonsense words for direct imitation and is designed to highlight significant markers of language impairment and reading difficulties. To standardize the GAPS, 668 children aged 3.4-6.6 were tested across the UK, taking into account population distribution and socio-economic status. The test was carried out by a range of health and education professionals as well as by students and carers using only simple, written instructions.
Results: GAPS is effective in detecting a range of children in need of further in-depth assessment or monitoring for language difficulties. The results concur with those from much larger epidemiological studies using lengthy testing procedures.
Conclusions: The GAPS test (1) provides a successful screening tool; (2) is designed to be administered by professionals and non-professionals alike; and (3) facilitates identification of language impairment or at-risk factors of reading impairment in the early educational years. Thus, the test affords a first step in a process of assessment and targeted intervention to enable children to reach their potential.
