我无法让 sbt-scoverage 发现和分析我们的测试。我们应该有很好的测试覆盖率（至少 80%）；所有测试都运行并通过。但覆盖率报告显示几乎为零的覆盖率（~ 3%）。
我唯一能想到的是，我们正在使用 specs2（以及 scalacheck）。我见过的大多数示例都使用 ScalaTest。
例如：我们在模型包中有四个类。即使测试结果表明它们已经过彻底测试，它们的覆盖率也为零：

[info]
[info]
[info] Total for specification TestCategoryModel
[info] Finished in 167 ms
[info] 3 examples, 300 expectations, 0 failure, 0 error
但我看到覆盖率肯定在运行：

但是覆盖率报告显然没有选择我们正在测试的类：

查看报告时，我看到模型包中的四个类完全未经测试。
我们的built.sbt 中有以下内容：
coverageEnabled := true
coverageMinimum := 80
coverageFailOnMinimum := true
显然，由于我们有上述设置，并且由于 scoverage 无法找到测试，我们会遇到构建失败：
[error] Coverage is below minimum [3.23% < 80.0%]
[error] (*:coverageReport) Coverage minimum was not reached
