scala - Gatling - 按顺序执行场景

Question

当我运行如下代码时:

setUp(
     scenario1.inject(constantUsersPerSec(1) during (1 second)),
     scenario2.inject(constantUsersPerSec(1) during (1 second))
).protocol()

两种情况同时开始。
需要改变什么才能一一运行？

Answer 1

关键方法是andThen在 Gatling 3.4+ 中，他们为其添加了新的 DSL，看起来像这样(取自官方文档)

setUp(
  parent.inject(injectionProfile)
    // child1 and child2 will start at the same time when last parent user will terminate
    .andThen(
      child1.inject(injectionProfile)
        // grandChild will start when last child1 user will terminate
        .andThen(grandChild.inject(injectionProfile)),
      child2.inject(injectionProfile)
    )
)
