FindBugs functionOnce a developer has developed a portion of the code, you can use FindBugs to check for code defects. Improve the quality of your code, but also reduce the number of bugs that testers have reported to you.
The static analysis tool promises to find bugs that are already in the code without the hassle of a developer. Of course, if you have many years of experience in writing, you will know th
showed that there was a quality problem in my team, And I've seen the same thing on many other teams.
The purpose of writing this article is to describe how my thinking about bugs and quality issues has changed gradually. This can help readers to better understand the quality problems resulting from the bug, and improve performance accordingly. And through some real story descriptions to see what the real problem is. (Let's say one thing: we don't a
Many years of testing experience often finds that some bugs cannot be fixed smoothly. These bugs often have four steps:
1. It was finally solved in the detected version, but it took more than a week in the middle.
2. Planned solutions will be implemented in subsequent versions.
3. I decided to never fix it, but it turned into a potential bomb and was forced to fix it in subsequent versions.
4. I decided to
During the software testing process, different people often test the same project, so repeated bug submission may occur, affecting the entire project and personnel:
This wastes the time and effort of testers and affects the testing progress.
A waste of time for developers to repeat bugs
If a developer calculates performance based on the number of bugs, the relationship between the develop
to consider the interface, whether the interface data processing problems, you need other developers to cooperate. and testers need to do their best to restore the scene at the time: environment, data, preconditions and test steps.
3. Testers have to reconfirm that the coverage and sophistication of test cases can result in a number of situations that are not reproducible: 1 environment; 2 code; 3 data. And the data can be summed up in the code fault-tolerant processing, the environment can be

Unfortunately, as a Team Project, users of this software cannot be limited to myself, and we also need to consider other target users. It's easy to write software for myself. I just need to use it myself. It's nice. User Experience is good. It doesn't matter if I don't care for myself. However, considering that this is a Team Project for other users at the same time, there are more things: good looking, there is enough prompt information, a
As we all know, fixing bugs are essential for all software projects in the future. Some unexpected problems exist for programmers when a software is delivered to a customer or handed over to a tester for testing. There are mature bug tracking systems, such as bugzero, bugzilla, and redmine.Solving bugs is a headache. I
for you are TextWriterTraceListener and EventLogTraceListener. TextWriterTraceListener writes the message to a stream, EventLogTraceListener writes the message to a eventlog. EventLog allows you to write debug and trace messages for your program into system event log records.

Simon Tatham, compiled by: DASNIntroductionPeople who have written software for the public have probably received very poor bug reports, such as:
Say "not good" in the report;
The contents of the report are meaningless;
The user does not provide sufficient information in the report;
Error messages are provided in the report;
The problem reported is due to the user's negligence;
The problems reported were due to errors in other procedures;
The problem reported is

CSS is a fairly easy-to-learn language compared to many programming languages. Its syntax is simple and straightforward, and because of its expressive nature, developers do not need to deal with complex logic. However, when you test your code in a different browser, the difficulty comes along. How to display browser bugs is a major challenge for most CSS developers. Your design displays well on one browser, but the layout may be fragmented on a differ
One aspect of team development is to allow individual developers to write and build unique code locally before merging all the changes into the central repository. Developers can test and debug the latest version locally, and they can ensure that all of their work code works with other colleagues, they can test the code manually, but a better way is to automate the process and provide instant feedback, and
, the watermark is used to set a conspicuous border or background (black or red in general) for debugging. This method is one of the most common methods for debugging CSS bugs and is still applicable to complex bugs. Economic benefits and environmental protection.
