Read local JSON file in XCUITest

问题

I am writing UI tests for iOS application. I want to read data from a local json file.

I am using the following code to get the path for my json file:

func testExample() {

    readJSON()
}

func readJSON(){
    let bundle = Bundle(for:myTestClass.self)
    if let path = bundle.url(forResource: "myurl", withExtension: "json"){
        print("Got the path")
        print(path)
    }
    else{
        print("Invalid filename/path")
    }

I have tried using the solution for the following stackoverflow question : Reading in a JSON File Using Swift. Didn't work!

Also, I had a look at the following Apple documentation: https://developer.apple.com/swift/blog/?id=37

Any help would be greatly appreciated!

First of all, you need to check the .json file is in the same target with the test file. If the file is in the main target, you have to use Bundle.main. However if it is in the same target with your test, use the below code.

let t = type(of: self)
let bundle = Bundle(for: t.self)
let path = bundle.path(forResource: "myurl", ofType: "json")

That's not how you read local json files from Bundle in iOS. It's done in the following way:

// "myUrl" is assumed to be your json file name 

if let pathStr: String = Bundle.main.path(forResource: "myurl", ofType: ".json") {
    print("json path: \(pathStr)")
}

I just found resources added to XCUITest targets will be placed under Bundle.main.resourcePath + "/PlugIns/<TARGET_NAME>.xctest/". However, I'm not sure if there were better ways to access them rather than hard-coding the sub-directory path.
