在蝗虫中将用户添加到测试过程的自定义速率

Question

我对 locust 和负载测试还很陌生，我需要编写一个负载测试，总共应该有 30 个用户，这些用户应该逐步添加到测试中，每分钟 3 个用户，同时有 30 个用户，测试应该是运行 for 5 minutes.Is 有什么办法可以做到这一点？

对于这个时间，足以添加 LoadTestShape class 到 locustfile.py，如下所示：

class StagesShape(LoadTestShape):
    """
    A simply load test shape class that has different user and spawn_rate at
    different stages.
    Keyword arguments:
        stages -- A list of dicts, each representing a stage with the following keys:
            duration -- When this many seconds pass the test is advanced to the next stage
            users -- Total user count
            spawn_rate -- Number of users to start/stop per second
            stop -- A boolean that can stop that test at a specific stage
        stop_at_end -- Can be set to stop once all stages have run.
    """

    stages = [
        {"duration": 60, "users": 3, "spawn_rate": 0.05},
        {"duration": 60, "users": 6, "spawn_rate": 0.05},
        {"duration": 60, "users": 9, "spawn_rate": 0.05},
        {"duration": 60, "users": 12, "spawn_rate": 0.05},
        {"duration": 60, "users": 15, "spawn_rate": 0.05},
        {"duration": 60, "users": 18, "spawn_rate": 0.05},
        {"duration": 60, "users": 21, "spawn_rate": 0.05},
        {"duration": 60, "users": 24, "spawn_rate": 0.05},
        {"duration": 60, "users": 27, "spawn_rate": 0.05},
        {"duration": 300, "users": 30, "spawn_rate": 0.05},
    ]

    def tick(self):
        run_time = self.get_run_time()

        for stage in self.stages:
            if run_time < stage["duration"]:
                tick_data = (stage["users"], stage["spawn_rate"])
                return tick_data

        return None
