Best Code Coverage Tools for TypeScript

IntelliJ IDEA analyzes your code, looking for connections between symbols across all project files and languages. Using this information it provides in-depth coding assistance, quick navigation, clever error analysis, and, of course, refactorings. ^⇧Space gives you a list of the most relevant symbols applicable in the current context. This and other completions are constantly learning from you, moving the members of the most frequently used classes and packages to the top of the suggestions list, so you can select them faster. Digs a tad deeper than Smart Completion and lists applicable symbols accessible via methods or getters in the current context. Say you're looking for a value of Project and only have the Module module declaration. Press ^⇧Space twice to get module.getProject() without any additional effort. Static members completion Lets you easily use static methods or constants. Offers a list of symbols matching your input and automatically adds required import statements.

On-the-fly error detection and suggestions for fixes, quick and safe refactorings with one-step undo, intelligent code completion, dead code detection, and documentation hints help all Go developers, from newbies to experienced professionals, to create fast, efficient, and reliable code. Exploring and understanding team, legacy, or foreign projects takes a lot of time and effort. GoLand code navigation helps you get around with instant switching to shadowed methods, implementations, usages, declarations, or interfaces implemented by types. Jump between types, files or any other symbols, or find their usages and examine them with convenient grouping by usage type. Powerful built-in tools help to run and debug your applications. You can write and debug tests without any additional plugins or configuration effort, and test your applications right in the IDE. A built-in Code Coverage tool will make sure that your tests don’t miss anything important.

Codacy is an automated code review tool that helps identify issues through static code analysis, allowing engineering teams to save time in code reviews and tackle technical debt. Codacy integrates seamlessly into existing workflows on your Git provider, and also with Slack, JIRA, or using Webhooks. Users receive notifications on security issues, code coverage, code duplication, and code complexity in every commit and pull request along with advanced code metrics on the health of a project and team performance. The Codacy CLI enables running Codacy code analysis locally, so teams can see Codacy results without having to check their Git provider or the Codacy app. Codacy supports more than 30 coding languages and is available in free open-source, and enterprise versions (cloud and self-hosted).

JavaScript test coverage made simple. Istanbul instruments your ES5 and ES2015+ JavaScript code with line counters, so that you can track how well your unit-tests exercise your codebase. The nyc command-line-client for Istanbul works well with most JavaScript testing frameworks, tap, mocha, AVA, etc. First-class support of ES6/ES2015+ using babel-plugin-Istanbul. Support for the most popular JavaScript testing frameworks. Support for instrumenting subprocesses, using the nyc command-line interface. Adding coverage to your mocha tests could not be easier. Now, simply place the command nyc in front of your existing test command. nyc's instrument command can be used to instrument source files outside of the context of your unit tests. nyc is able to show you all Node processes that are spawned when running a test script under it. By default, nyc uses Istanbul's text reporter. However, you may specify an alternative reporter.
