In their own words
Codecov
Codecov provides code coverage reporting and development insights, with tools for test analytics, JavaScript bundle monitoring and pull-request checks. It reports line, branch, project and patch coverage in XML, JSON and TXT formats. Pull-request annotations and coverage gates help teams review changes; Status Checks can block a merge when coverage is underperforming. Historical trends show coverage over time. Test Analytics reports failures and detects flaky tests, while Bundle Analysis flags oversized JavaScript bundles in pull requests and tracks bundle-size changes. The homepage also describes AI features for generating unit tests and reviewing pull requests. Developers can use a command-line interface or VS Code extension for coverage information and visualization. Integrations include GitHub, GitLab, Bitbucket, CI platforms and Slack. Codecov lists a broad range of supported languages, including C#, Go, Python, JavaScript, Rust and Swift. It is available through web, API, extension and self-hosted options. The free Developer plan has upload limits for private repositories; paid plans start at $5/user/mo, and a 14-day trial is available.
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.
