# What’s coming in Test Lint 1.5

By Roy Osherove October 14, 2010 In [Unit Testing](https://osherove.com/blog/category/unit-testing)

**Historical article** · Originally published October 14, 2010; technical details may be outdated.

[Test Lint](http://site.typemock.com/test-lint/) is an “as you type” parser that detects common readability, maintainability and trust anti-patterns in your unit tests. the addin for VS **is free**. there is also [a command line version](http://site.typemock.com/typemock-test-lint-pro) that you can use in your automated builds.

Here’s a sneak preview of things to come in [Test Lint](http://site.typemock.com/test-lint/) next month ([here are the still unfinished new docs](http://docs.typemock.com/lint/##LintHelp.chm/test_lint_rule_review_referenc.htm)):

- we added 3 categories for rules – **Trust, Readability, and Maintainability**

We’ve added **10 new rules to Test Lint**, that detect more “advanced” yet common problematic scenarios:

**New Trust Related Issues:**

- Avoid hand rolled mocks or stubs that contain custom logic (hard coded values or pure logic)
- We’ll try to detect when you [put production logic in your unit test](http://docs.typemock.com/lint/##LintHelp.chm/avoid_putting_production_logic.htm), and give you a hint about it
- We’ll help make sure you [separate unit from integration tests](http://weblogs.asp.net/rosherove/archive/2008/05/31/unit-testing-vs-integration-testing-the-restaurant-analogy.aspx), by detecting integration tests in a project that doesn’t have the word “integration” at its subject.
- Avoid Random Generation in tests: your test will keep changing on every run.

**new Readability Rules:**

- Avoid confusing mocks and stub variable names
- Don’t create fakes in setup methods

**New Maintainability rules**

- Prefer factory method to create objects under test
- Avoid over specification in test (calling verifyAll on mocks)

**New Isolator Specific Rule**

- Avoid calling “new” inside “whencalled” calls
