If statement in Postman tests
提问by Gene Truuts
I work in Postman and I want to build the test construction like that:
我在 Postman 工作，我想构建这样的测试结构：
var login_status = pm.environment.get("LOGIN_STATUS");
var jsonData = pm.response.json();
pm.test("TESTS", function () {
if (login_status === 1) {
pm.expect...(test 1);
}else if (login_status === 2) {
pm.expect...(test 2);
}else if (login_status === 3) {
pm.expect...(test 3);
but it doesn't work for me as I want.
但这对我不起作用。
In my logic, Postman should check the login status and use only one pm.expect... accordingly to login_status value.
在我的逻辑中，邮递员应该检查登录状态并根据 login_status 值只使用一个 pm.expect...。
How can I use the if statement in Postman? Thank you!
如何在 Postman 中使用 if 语句？谢谢！

The comparison operator you are using is returning falseas it's checking for the same type, try using ==rather than ===.
您正在使用的比较运算符正在返回，false因为它正在检查相同的type，请尝试使用==而不是===。
The values stored in the Postman environment file is a stringand you're doing a strict equal against a number, in the test.
存储在 Postman 环境文件中的值是 astring并且您number在测试中对 a 进行了严格等于。
You could also try changing the numbervalue to a stringvalue like this login_status === "1"or use strict inequality so the type you use doesn't matter, like this login_status !== 2.
您还可以尝试将number值更改为这样的string值login_status === "1"或使用严格的不等式，这样您使用的类型就无关紧要了，就像这样login_status !== 2。
You could even just use a parseInt()function when you get the value from the file.
parseInt()当您从文件中获取值时，您甚至可以只使用一个函数。
parseInt(pm.environment.get("LOGIN_STATUS"))
It's completely up to you and the way you want to construct the check.
这完全取决于您和您想要构建支票的方式。
