Only tests in embedded packages are automatically included by the Test Runner. Embedded packages are folders that are added directly into the Packages folder at the root of the project. This does not include local packages, which are referenced by path and live outside the project.
Most packages should not be embedded, instead adding them to your project involves a few steps:
"dependencies" and "scopedRegistries" add:"testables": ["com.company.package"]com.company.package is the package name that contains your tests."testables" entry, add your package to it like:"testables": ["com.company.package", "com.company.other-package"]See Adding tests to a package for more information.
