What is automated testing?

It is a practice of transforming human testing behavior on software into testing behavior performed by machines.

For example, web automation testing, simulating people to operate the software interface, frees people from simple and repetitive labor. The essence is to use code to test another piece of code, which is a kind of software development work. Test objects are updated for changes, therefore, there are additional maintenance costs.

What are the classifications of automated testing?

Classification by test purpose:
functional automation test; performance automation test; classification by test object;

Web application testing:
APP testing; interface testing; unit testing

Why do you need automated testing?

It can replace a large number of manual and mechanical repetitive operations, and test engineers can spend more time on use case design and new function testing

It can greatly improve the efficiency of regression testing, which is very suitable for the agile development process;
it can make better use of unattended time to execute tests more frequently;
it can efficiently implement some types of tests that cannot be completed or costly by manual testing, such as: 7*24 hours of continuous system stability testing and stress testing of high-concurrency scenarios;
it can ensure that each operation is consistent and repeatable, and will not be affected by human emotional factors;

Automated testing of Postman interface

1. Create a new collection
to classify the interfaces to be tested in a unified way.

2. Create a new interface
The following is what I added

3. Fill in the automated test script.
For example, you need to test several points
with HTTP status code 200;
the returned json code is 0;
the interface return time is not less than 1000 milliseconds;

The script is as follows

//查看httpCode码
tests["接口状态码200"] = responseCode.code === 200;
//判断请求时间
tests["返回时间小于1000毫秒"] = responseTime < 1000;
//返回body转json
var data = JSON.parse(responseBody);
//检查json数据
tests['code码必须为0']= data.code==0

The test results are as follows

4. Enter all the interfaces
and then I will perform this test on all the interfaces, and enter these interfaces, as follows

5. Execute the automated test
and click the Run button of the collection

The following interface pops up, you can fill in the corresponding parameters, here I use the default

Click Run, the execution results are as follows
