Uniapp automated test learning

Environmental Science ： It's normal uniapp project , Build a test environment by installing plug-ins , Instead of cli The way

Question 1 ： Tips node Of binding.node The problem of

After installing the plug-in , Tips node Of binding.node The problem of , Currently installed is node.js yes v14 Version of , Install after uninstall v12 edition , No more errors

Question two ： There is no option to run test cases by right clicking

the reason being that vue How to write it , establish xxx.spec.js The test file , There is no option to run test cases by right clicking . Change it to xxx.test.js , Right click to select run test case

Question 3 ： import when , newspaper Cannot use import statement outside a module

See vue Component unit tests , In the test file , have access to import To introduce modules , But in uniapp Of , xxx.test.js In file , Use import To introduce , Will be submitted to the ：

Cannot use import statement outside a module

detail as follows ：

({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,jest){import { shallowMount } from "@vue/test-utils";

It seems to be the whole xxx.test.js The file encapsulates a function Method , So use import It's a mistake , Need to use require To introduce

1：import Loaded at code compile time , So it has to be at the beginning of the file ,require Loaded at code run time , therefore require In theory, it can be used anywhere in the code , therefore import Better performance .
2：import When the introduced object is modified , The source object will also be modified , Equivalent to light copy ,require When the introduced object is modified , The source object will not be modified , The official website is called copy , We can understand it as a deep copy .

Then I refer to other people's articles ：uniapp automated testing

Tested according to the blogger's writing ：.test.js The contents are as follows

.child-title Is one of the introduced sub components class, The operation results are as follows ：

thus , It can be regarded as a simple test process , For the preparation of test documents and jest Usage of , To be studied
