OpenClover OpenClover Developer(s)Ĭlover is a Java code coverage analysis utility bought and further developed by Atlassian. EclEmma Eclipse (software) Code Coverage Plugin, was formerly EMMA based.SonarQube JaCoCo plugin - one of the defaults for coverage analyses within the code quality management platform SonarQube.Unlike Cobertura and EMMA it fully supports Java 7, Java 8, Java 9, Java 10, Java 11, Java 12, Java 13, Java 14, Java 15, Java 16 and Java 17. Files from multiple runs or code parts can be merged easily. like Cobertura and JCov prior to execution (offline)Īnd can be configured to store the collected data in a file, or send it via TCP.like JCov on the fly while running the code with a Java agent.In contrast to Atlassian Clover and OpenClover, which require instrumenting the source code, JaCoCo can instrument Java bytecode using two different approaches: JaCoCo offers instructions, line and branch coverage. It was developed as a replacement for EMMA, under the umbrella of the EclEmma plug-in for Eclipse. JaCoCo is distributed under the terms of the Eclipse Public License. JaCoCo is an open-source toolkit for measuring and reporting Java code coverage. Public API and SPI which makes it possible to implement custom filtering and/or mining the coverage data.JCov has a few more distinctive features which include, but are not limited to: Dynamic instrumentation which is done on the fly by means of Java agent.Static instrumentation which is done upfront, changing the tested code.JCov works by instrumenting Java bytecode using two different approaches:
JCov implements two different ways to save the collected data: JCov is capable of reporting the following types of code coverage: JCov has become open-source as a part of OpenJDK code tools project in 2014.
JCov is distributed under the terms of the GNU Public License (version 2, with the Classpath Exception).
JCov is capable of measuring and reporting Java code coverage. JCov is the tool which has been developed and used with Sun JDK (and later Oracle JDK) from the very beginning of Java: from the version 1.1.
