This article analyzes "what are the main reasons for the collapse of APP?" The content is detailed and easy to understand. Friends who are interested in "what is the main reason for the collapse of APP" can follow the editor's train of thought to read it. I hope it will be helpful to you after reading. Let's go deep into the knowledge of "what is the main cause of APP collapse" with the editor.

First, what kind of scenarios are prone to crash problems

Recently, I have been thinking about what kind of problem can easily lead to collapse-that is, abnormal thinking. For example, I watched an American TV series called "Rookie Old Police" two days ago, in which the protagonist John Nolan escaped because he didn't stop the fugitive's car with a police car. what does this scene have to do with the test? First of all, normal people will avoid collisions with others when driving on the road, which is like the main flow of testing functions, and they will not input at random; but the police are different, they will do everything they can to catch fugitives, just like the abnormal thinking in the testing process, thinking about how to operate so that the function is not good.

Baodian I. abnormal operation

All kinds of abnormal operations may lead to program crash, although customers basically use APP according to the process, but for testers, finding potential crash problems and ensuring product quality is the best summary of our work. Most of the specific function crash problems summarized below are caused by abnormal operations, such as adding large-capacity pictures, long pictures, incomplete pictures and so on.

Baodian II, a certain function switches back and forth between front and back, which can easily lead to collapse.

For example, during video playback, you switch to the background and then switch back.

Baodian III. Boundary value class collapse

The so-called boundary value problem is the maximum value that the test function can withstand, for example, if a picture supports a maximum of 5m, you upload a picture with a maximum of 5m, and the text box supports a maximum of 300 words, you enter content greater than or equal to 300 words.

Baodian IV. Click on a specific function many times

This is more common, multiple clicks on the back button on the page, multiple searches, multiple clicks on the toggle button, multiple clicks on the share button, etc., will cause the program to crash.

Baodian V, functional operation under weak network conditions

Baodian VI. Fast operation when the page is not fully loaded.

Second, the collapse of specific functions

2.1, Video / Voice

1) during full-screen video playback, click the full-screen button and the return button in the upper left corner many times, and the system crashes

2) when the video is playing in full screen, the system crashes when you click the full screen and return to previous buttons at the same time.

3) the system crashes when the video is played horizontally and vertically.

4) in the process of video playback, repeatedly adjust the double speed to crash

5) switch to the background and then back to the foreground during video playback, and the playback is not successful

6) switching chapters multiple times during video playback APP flicker

7) after being paused by other software during video playback, you can switch back to the playback page and click to continue.

8) the downloaded video crashes after clicking to delete it.

2.2, camera / scan / profile picture

1) scan the interface to enter the album and select a picture of more than 10m to flash.

2) No album permission to modify avatars to access albums

3) the avatar uploaded to the long picture crashed

4) the avatar uploaded incomplete picture crashed

5) Click the photo button, switch to the background, then switch to the foreground, and click to select the picture to flash.

2.3, text box / search

Paste the content in the input box and select the copy program to flash.

2) enter all the text in the search interface and add flashback.

3) after the search is successful, search APP crash again

4) enter special characters many times to search, and app flicker

5) Click on the search results interface to cancel the program flashback.

2.4, page operation

1) exit immediately after entering the page, and then click on other columns

2) continuously return to the previous page

3) enter the interface and load all the time. Click app after kill app, and the page will flash when it opens.

4) when there is a lot of content in the interface, it slips up and refreshes and then slides down. If you click on any record, the interface card owner will flash back.

2.5. Sharing function

1) share Wechat successfully and return to the app. Click the share button again to flashback the app.

2) operate the message sharing button multiple times

3) after sharing the content successfully, such as opening a link in qq to indicate that the story does not exist.

4) Weibo authorizes login and crashes several times

Finally, these scenarios and operations need temporary flexibility to have a better effect. In the case of weak network, I think it is easier to click on a function many times, and the program often switches between foreground and background.

This is the end of what is the main reason for the collapse of APP. I hope the above content can improve everyone. If you want to learn more knowledge, please pay more attention to the editor's updates. Thank you for following the website!
