groovy单测自动生成

以交易核心trade举例

前置准备

groovy和mockito单测自动生成_第1张图片

注意:xxx.ftl需要放在测试resources的template下

如果服务没有freemarker需要补充pom依赖

<dependency>
	<groupId>org.freemarkergroupId>
	<artifactId>freemarkerartifactId>
	<version>2.3.21version>
	<scope>testscope>
dependency>

使用

groovy和mockito单测自动生成_第2张图片

将想要写的单测和自己的名字输入执行
注意:如果是新服务导入需要对项目进行clean再编译,因为模板是读取target/test-classes/template/xxx.ftl

结果

单测地址已生成
