* Version control - IntelliJ IDEA provides a unified interface for major version control systems including Git, SVN, Mercurial, CVS, Perforce, and TFS. * Build tools - IntelliJ IDEA supports Maven, Gradle, Ant, Gant, SBT, NPM, Webpack, Grunt, Gulp and other build tools. Seamlessly integrated, these tools help automate compilation, packaging, running tests, deployment and other activities * Test runner and coverage - IntelliJ IDEA lets you perform unit testing with ease. The IDE includes test runners and coverage tools for major test frameworks, including JUnit, TestNG, Spock; Cucumber, ScalaTest, spec2, and Karma. * Database tools - Take advantage of intelligent coding assistance when editing SQL; connect to live databases; run queries; browse and expert data; and even manage your schemes in a visual interface–right from the IDE. * Language injection - Brings coding assistance for a selected language to expressions and string literals in another one, complete with all advantages you would normally have. For example, you can inject fragments of SQL, XPath, HTML, CSS, or JavaScript code into Java String literals. * Cross-language refactorings - Knowing everything about usages of a symbol, IntelliJ IDEA offers extremely effective, thorough refactorings.
