A First Look at the "Just Asked" Series - Java+Playwright Automation Testing - 5 - Creating the First Automation Script (Detailed Tutorial)

1. Introduction

The first few macro introduced two (java and maven) environment to build and browser startup method, this article macro will introduce the first automated test script. The front of the environment are built successfully, the browser is also driven successfully, then we are not in a hurry to learn other content, the first macro to build a good environment to create the first complete automated test script, so that the partners or children in advance to feel the feeling, but also in order to stimulate everyone's interest in learning.

Hong's personal experience is: automation scripting is relatively easy, the biggest difficulty to go how to write test assertions. Automation testing, the most important still falls on the test above, rather than automation, automation is only a means. Assertions are written in a way that tests whether a test engineer has considered all aspects, reflecting the level of your use case writing.

2. Test cases

Many children's shoes or partners may have such a misunderstanding: automated testing is not required to design test cases. In fact, it is not it is also necessary to design test cases, and then according to the use of scripting and assertion of the case, but the use of the case in the form of code, and the machine happens to be able to recognize the code, the code will run up, in fact, is in the implementation of your use case, but by the machine to help you automatically. Well, cut the crap and start talking about the macro to do today's test is: open Baidu, enter Beijing - Hong search, verify that the open link has no Beijing - Hong blog park link.

Test case: open the Baidu home page, search: Beijing - Hong brother, and then check the search list, there is no Beijing - Hong brother blog garden link. Subsequent articles in order to avoid unnecessary trouble and errors, Hong are in the maven built environment for practical demonstration.

2.1 Steps

1. Launch the browser

2. Open the Baidu home page:

3. Determine whether this page is a page we know in advance

4. Position the search input box, record the id of the input box element positioning expression: #kw

5. Locate the search submit button (Baidu), get the id location expression: #su

6. In the search input box enter: Beijing - Hong, point Baidu this button!

7. In the search results list to determine whether the existence of Beijing - Hong brother blog garden this link

8. Exit the browser to end the test

2.4 Running the code

1. Run the code, right click Run AS->java Application, you can see the console output, as shown below:

precedent：Astrings andBComparison with strings:
if((B)){

}
come (or go) backtrue maybefalse.
