期望不要使用参数抛出函数 - Jasmine [英] Expect not toThrow function with arguments - Jasmine
问题描述
我有获得3个参数的函数。我想检查一下这个函数没有抛出错误。
我做了这样的事情:
I have function that gets 3 arguments. I want to check that this function not throwing an error. I did something like this:
expect(myFunc).not.toThrow();
问题是 myFunc
需要获取参数。我如何发送参数?
The problem is myFunc
need to get argument. How can I send the arguments?
PS我试图传递它的参数但是我得到错误 myFunc(arg1,arg2,arg3)
不是函数。
P.S I tried to pass it argument but I got error that myFunc(arg1, arg2, arg3)
is not a function.
推荐答案
toThrow
matcher要求函数作为参数传递给 expect
,这样你就可以简单地将你的函数调用包装在匿名函数中:
toThrow
matcher requires function to be passed as argument to expect
so you can simply wrap your function call in anonymous function:
expect(function() {
myFunc(arg1, arg2, arg3);
}).not.toThrow();
您还可以使用 bind 创建函数的新版本,调用后将通过参数传递:
You can also use bind to create new 'version' of your function that when called will be passed provided arguments:
expect(myFunc.bind(null, arg1, arg2, arg3)).not.toThrow();
