In their own words
Coverlet
Coverlet is a free, MIT-licensed code coverage framework for modern .NET SDK-style projects. It measures line, branch, and method coverage across Linux, macOS, and Windows. Before tests execute, Coverlet instruments assemblies, records sequence-point hits, restores the original assemblies, and writes coverage results. Drivers are available for Microsoft Testing Platform, the .NET global tool, VSTest, and MSBuild. The Microsoft Testing Platform driver can emit JSON, LCOV, OpenCover, and Cobertura reports. Depending on the driver, teams can merge reports, validate coverage thresholds, and support deterministic builds. Collector and MSBuild packages use VSTest; Microsoft Testing Platform projects instead use coverlet.MTP, which requires the .NET 8.0 SDK or newer. Cake.Coverlet and Visual Studio viewing extensions are also listed. Coverage gates are supported, and bugs or feature requests go through the repository issues section.
EclEmma
EclEmma is a Java code coverage tool that brings coverage analysis into the Eclipse workbench. It supports local Java applications, Eclipse and RCP applications, Equinox OSGi, JUnit, TestNG, Eclipse plug-in and RAP tests, SWTBot tests, and Scala applications. Its Coverage view summarizes results by project and lets developers inspect methods; source editors highlight covered and uncovered code. Coverage summaries can use instruction, branch, line, method, type and cyclomatic complexity counters. Users can switch among coverage sessions or merge results from separate test runs. EclEmma imports JaCoCo.exec data and exports reports in HTML, XML or CSV, as well as JaCoCo execution data files. It is based on JaCoCo and can be installed through the Eclipse Marketplace Client, an update site or manually. The free plug-in is listed at free under the Eclipse Public License 2.0. It requires Eclipse 3.8 or higher, Java 1.5 or higher, and Eclipse Java development tools; the project states that it has no operating-system dependency. Its Eclipse integration focuses on individual developers, with JaCoCo integrations suggested for automated builds.
