With the rise of the mobile Internet, APP testing is getting more and more attention! Because of its open source nature, the Android system has widely spread test tools and test methods, but the privacy of the iOS system makes it a bit troublesome to execute many tests.
01 Automated testing
1. UI Automation
UIAutomation is a UI automation ios real device testing provided by Apple, written in JavaScript.
Based on UIAutomation, there are extended tool frameworks and driver frameworks. The extended framework provides many useful js tools in the way of JavaScript extension library, and the injection framework usually provides some Lib or Framework, requiring testers to import these contents in the code project of the application under test, and the framework can complete the comparison through them. app driver.
Driven UI Automation uses the UI Automation library at the bottom of ios real device testing, and drives UI Automation through TCP communication to complete ios real device testing. In this way, the language for editing scripts is no longer limited to JavaScript.
2. XCTest
XCTest is a simple and powerful test framework introduced by Apple in iOS 7 and Xcode5, which is integrated in Xcode and used to write test code. It provides various levels of ios real device testing.
XCTest tests are very simple to write and follow the xUnit style. When Xcode creates a project, it uses XCTest by default, and creates two Targets, Unit Test (unit test) and UI Test (interface test) by default;
Among them, Unit Test is mainly used to test most of the basic functions of the code, such as most Model class and method tests, business logic tests, network interface call tests, and so on.
UI Test generally considers the user's interaction process, simulates the user's interactive operation, uses the UI recording feature of XCTest to obtain a series of view elements and operation events on the interface, and then triggers the event in the test method.
So this is a framework that can provide various levels of ios real device testing, such as unit testing, automated testing, performance testing, etc.

Xiaobai must know these three inspection tools when buying a second-hand iPhone.
The first one is Aisi Assistant, which is also the most commonly used tool for everyone. You need to download the Aisi Assistant software on your computer first, and then connect the mobile phone to be inspected to the computer with a data cable to get a complete inspection report. Including the sales type of the mobile phone, the sales place, whether the hard disk, battery, camera, etc. have been replaced.
However, as a third-party ios real device testing, Aisi Assistant is not 100% reliable, and merchants may use special means to modify the inspection results of Aisi Assistant.The second type is an hourglass inspection machine similar to Aisi Assistant. Also connect the mobile phone to the computer and check the machine through the software. If the test score is 100, it means that there is nothing wrong with the mobile phone. But it also has the same problem as Aisi Assistant.

The third type is the gsx machine inspection. You need to use the serial number of the mobile phone to query the original information of the device. You can also query the sales type, sales place, memory capacity, whether there is a network lock, activation lock, etc., although you cannot check whether the accessories are Original, but it is relatively convenient to check, you can do gsx on the merchant before buying, or ask the merchant to provide the serial number. Secondly, as long as the serial number is real, the result of gsx detection is the most authentic and reliable.
