. NET program run process problems

1. Data compatibility

The development of functional modules will affect the updating and reflection of historical data and new data. For example, development function 007,007 supports the principle that the amount is variable and the quantity is immutable. Historical data are the principle of variable quantity and immutable amount. At this point, a problem arises.

2. Integration Testing

The development and maintenance of the function module will affect the problem caused by the overall change of the unit module process. For example, the development of a function 006 save with a check function, the number must not exceed 10, so the first time you save the changes, the save really no problem, but the changes found no check.

3. Deep black hole

The development of a function 001, using the underlying method A, the underlying method A also contains method B, the normal process runs through, test normal on-line. After half a month, customer feedback, function 003 has a problem, a check for a long time, and finally found to be ....

The reason is that function 001 execution method A does not have a problem, called Method B, generated a lot of garbage data, and the original method B is not referenced anywhere, and function 001 happens to meet the conditions of the execution method b

4. Multi-point triggering

b developed a function 005, after the perfect test, on-line finally succeeded, a year later, customer service feedback, there has been a big problem. One of the clients received 2 grants. After technical investigation, the 2 grant operation time is 3 seconds,

But the problem in the test environment repeated verification, simply can't reproduce, and then C ...

Open 2 pages to operate, one page has been updated, the other page does not close, this page operation and then click on another page, there are 2 times grant.
