Today, let's talk about several reasons why the app crashed.
The first reason is that a function of an app switches back and forth in the background of the mobile phone. For example, when we catch up with a drama or watch a movie and have WeChat or QQ messages coming in, many people will click in to reply to friends' messages, and then most people will choose to switch back to video software. This can easily lead to the collapse of the app.
The second reason is that an app has a large number of users in the same time period, and the server can't bear it, and the app will crash. For example, whenever a star suddenly releases a news of marriage and children, many netizens want to flood in? Eat melons? This situation will make the app crash. Every year, when students register for the postgraduate entrance examination, the postgraduate entrance examination network will not be able to squeeze in and register, and netizens will also say that the research recruitment network has collapsed again.
The third reason is the collapse of boundary value classes. For example, when posting a message, the application text box allows 300 words to be posted, but users who enter more than 300 words can easily cause the application to crash.
The fourth reason is to click a function many times. For example, when submitting a picture, the app does not respond, and when the user is in a hurry, he will always click to submit the picture. This practice of clicking a function many times will lead to the crash of the app.
The fifth reason is that a series of operations will also cause the app to crash when the network is not smooth and the page is not full.
When the app crashes, programmers need to check the bug to fix it, and in some cases, they can also solve it by adding servers.
