Developers should do your own testing or not? In Software Development, developers have a major role as they design, code, and build software. They were also asked to do a 'white box' testing, code testing means.
They executed Unit Testing (testing individual units of source code to verify whether it meets the specifications and behave as expected) and Integration Testing (testing related program or unit code to ensure that some parts of the system interact well with other parts of the system), This test checks the function, performance, and reliability program.
However, it may still not be enough to ensure that the program does not have any bugs or errors.
Therefore developers have learned how to rely on Assurance (QA) Quality Tester to find defects and bugs. But even QA could be wrong.
There is then a tendency to move in the direction of developer testing based rather than based testing QA. To determine the best alternative, you have to know what good QA and test developers is and require.

Depending on the team, the developer will be required to perform a minimum or unit testing to generate automated, integrated, code-based test. More often than not, however, developers do not want to waste the time to build a development test in favor of creating new features.
One reason for this is that the developers only work in one part of the application code and may not understand all the terms. If the requirements are misunderstood, no matter the depth of the test, they will never find fault.
Another reason for this is that some developers think that creating a test unit was too complicated to do repeatedly, even when automatically. Basically, testing slows the development process and reduces the productivity of coding.
Some developers also may be too optimistic in their program. They will see them as a perfect code and power, as a result, ignoring other details of the program or will skip the bug.
In addition, some parts of the program may also not be tested because, once developers have noticed that certain parts work, he will not re-test it. He will always assume that it is working properly and does not affect other operations.
On the other hand, developers will be most familiar with the program and their own code. That's why some strict developers test their code to get rid of the error and check the functionality of the application. Developers know the best program and will have the satisfaction of seeing it pass the required specifications.
In the long term, the developers know that if they make a test, it will save more than wasted because of reduced time on the issue of the release and production and reduce defects.
All in all, many developers are not testing due to the complicated and repetitive and they may not understand the requirements of the application. However, developer testing is an important part of the QA program when it is well managed and will ensure fewer defects.

QA testing to make sure that the bugs, errors, and defects detected in the software. It skillsets are very different from those of developers.
QA testers have a wider knowledge of the application system and history, giving them the ability to fix any problems that arise. Testers execute an in-depth analysis of the application and repeat the process until the bug is fixed.
QA testing is primordial and valuable, whether as a support role for the development team or as an independent entity. QA testers usually work within a team of developers because it increases productivity. They give a human perspective that enhances the success of the test code.
QA testers also provide test cases and plans that can guarantee a source of additional documentation to training and customer use. These tests include all the information needed for developers to understand the function of the application. For many software development teams, has a QA tester is absolutely necessary.
In conclusion
Therefore, who should do the testing? A balanced approach is probably the most appropriate. Indeed, developers and testers work best together, and will both save time and make the program more reliable.
