在 Postman 中请求重用 [英] Request reuse in Postman

问题描述

我们的团队希望自动化我们的 REST API 测试.现在，我们有一组 Postman 请求，并让它们手动跳过.

Our team wants to automate our REST API testing. Right now, we have a collection of Postman requests and make them jump through hoops manually.

我们可以为每个测试场景创建一个集合/文件夹，但这意味着大量重复.我们的 API 仍在大力开发中，我真的不想在更改后的 20 个地方修复相同的东西.

We could create a collection/folder for each testing scenario, but that would mean a ton of duplication. Our API is still under heavy development and I really don't want to fix the same thing at twenty places after it changes.

我希望每个端点请求在一个集合中只有一次，并且有某种独立的逻辑可以以任意顺序执行它们.我知道 Postman 不支持请求重用，所以我正在寻找至少一种 hacky 的方式来做到这一点.

I would like to have each endpoint request only once in a collection and some kind of independent logic that can execute them in an arbitrary order. I know Postman doesn't support request reuse in any clean way, so I am looking for at least a hacky way how to do it.

推荐答案

创建一个文件加载到 Postman Collection Runner，结构如下:

Create a file to load into the Postman Collection Runner, with the following structure:

[{
    "testSequence": ["First request name", "Second request name", "..." ],
    "anyOtherData":  "Whatever the request needs",
    "evenMoreData":  "Whatever the request needs",
    "...":           "..."
},{
    "testSequence": ["Login", "Check newsfeed", "Send a picture", "Logout" ],
    "username":  "Example",
    "password":  "correcthorsebatterystaple",
},{
    "...": "keep the structure for any other test scenario or request sequence"
}]

将所有测试序列放入该文件中，然后让 Postman 在每个请求后检查列表并决定接下来要执行什么.这可以做到 e.G.在整个集合的测试块"中:

Put all your test sequences in that file, then make Postman check the list after each request and decide what to execute next. This can be done e. g. in a "tests block" of the whole collection:

// Use the mechanism only if there is a test scenario file
// This IF prevents the block from firing when running single requests in Postman
if (pm.iterationData.get("testSequence")) {

    // Is there another request in the scenario?
    var sequence = pm.globals.get("testSequence");
    if ((sequence instanceof Array) && (sequence.length > 0)) {

        // If so, set it as the next one
        var nextRequest = sequence.shift();
        pm.globals.set("testSequence", sequence);
        postman.setNextRequest(nextRequest);

    } else {
        // Otherwise, this was the last one. Finish the execution.
        postman.setNextRequest(null);
    }
}

如果您的请求需要在不同的运行过程中使用不同的数据，您可以在输入文件中定义数据并将其用作 请求中的变量.

If your requests need to use different data during different runs, you can define the data in the input file and use them as variables in the request.
