在空手道中使用 cURL 实现 API 自动化

Question

I'm new to Karate

I'm automating an API test where I need to upload a large file >50MB When I do so with Karate I get an error "Broken Pipe" and according to this question Broken pipe (Write failed) when testing > max allowed Content-Length I could use "cURL" for this request.

It's working fine as follows (with hardcoded data):

* def result = karate.exec('curl -L -X POST "URL" -H "Authorization: Bearer MYTOKEN" -F "file=@"PATH""')

However, I'm having issues with the syntax when passing variables I need to pass the URL, token, and path as variables and not hardcoded text since I will be reusing this test for multiple landscapes.

How would I go about it? Thanks,

Think of the Karate syntax as very close to JavaScript. So, string concatenation works. For example:

* def myUrl = 'https://httpbin.org/anything'
* def result = karate.exec('curl ' + myUrl)

And a nice thing is that JavaScript Template Literals work:

* def myUrl = 'https://httpbin.org/anything'
* def result = karate.exec(`curl ${myUrl}`)

Also note that the karate.exec() API takes an array of command-line arguments. This can make some things easier like not having to put quotes around arguments with white-space included etc.

* def myUrl = 'https://httpbin.org/anything'
* def result = karate.exec({ args: [ 'curl', myUrl ] })  

You can build the arguments array as a second step for convenience:

* def myUrl = 'https://httpbin.org/anything'
* def args = ['curl']
* args.push(myUrl)
* def result = karate.exec({ args: args }) 

Note that conditional logic and even an if statement is possible in Karate: https://stackoverflow.com/a/50350442/143475
