4.开始生成

mvn evosuite:generate
mvn compile -DmemoryInMB=2000 -Dcores=2 -Dcuts=com.xxx.xxx.api.service.impl.CurriculumServiceImpl-DtargetFolder=src/test/java/evosuite evosuite:generate evosuite:export
compile 表示编译。evosuite 是基于编译后的 .class 文件生成用例的，所以需要先编译。
-DmemoryInMB=2000 表示使用 2000MB 的内存
-Dcores=2 表示用2个 cpu 来并行加快生成速度
-Dcuts=com.xxx.xxx.api.service.impl.CurriculumServiceImpl 表示只针对 com.xxx.xxx.api.service.impl.CurriculumServiceImpl 这个类生成用例。多个用例可以用英文逗号分隔
-DtargetFolder=src/test/java/evosuite 表示生成的用例放到 src/test/java/evosuite
evosuite:generate 表示执行生成用例
evosuite:export 表示导出用例到 targetFolder 的值所在的目录中
 
Idea插件使用

1.下载 evosuite-1.0.6 jar
2.idea安装evosuite插件
3.配置


2.evosuite -jacoco

注意：EvoSuite的bytecode instrumentation和类似Jacoco这类工具在bytecode instrumentation上有可能有冲突，导致最后的覆盖率统计都是0(修改separateClassLoader = true为false)
