Once thought that a software in writing, just a few people together, the knowledge of the mind collide Sparks, a software came out, but a software project development also need to manage. Now the scale of software development is increasing, software project management has in

the goal question, but does not discuss the quality question. In other words, the classic textbook always focuses on how to complete projects faster, reduce resource usage, and achieve more functionality.However, even if this relationship is balanced, the results of the project can still create a natural handicap. Because the goal may be established in the balance, but the quality is controlled in the process. Even with the balance of time, resources and functionality, even if customers, projec

Several settings to note in the software after switching the main memory of the Nios II CPUSometimes, we may face a situation where:1. We create a SOPC system and set the reset address and the exception address of Nios II in the Qsys to point to SRAM;2. We have created the correct Nios II software engineering and are able to operate properly3. Due to a demand (su

After the unit test, the machine status remains the same (delete the temporary file or directory created by the unit test during the teardown phase) 4. Unit tests are fast and produce repeatable, consistent results 5. Independence (when other modules are time-consuming or unstable, you can artificially construct the data for unit testing) 6. Unit tests should overwrite all code paths (public and private fun

In addition, as a software engineering practitioners, our knowledge reserves must be as much as possible, like the author, ancient prose poetry, the same s

-up strategies are setCons: Middle tier testing is not sufficientAdapt to most software development projects5) Backbone IntegrationAdvantages: With the advantages of sandwich integration, it is more suitable for large complex project integration.Disadvantage: The structure and interdependence of the system must be carefully analyzed, the driving and pile development is large, the strategy of the Big Bang is adopted locally, and some interfaces may not

development of the drive module is large.　　　　The high-level tests were postponed to the end, and the overall design error was found later.Become more complex when integrated into the top layer(3) Sandwich integration: Sandwich integration (Sandwich integration) is a hybrid incremental test strategy that combines the advantages of both top-down and bottom-up integration methods. This method of pile module and drive module development work is relatively small, but the cost is to a certain extent

break it down and make it much easier. We also have a lot of difficult things to do in life, but when we break them down we feel very easy. An efficient program is inseparable from a good data structure and algorithm. Data structure is the basis of the program, so to make a good program is not to learn how much programming skills but to learn good data structure and algorithms. In the user interface design this piece also needs to work hard, because this can make the user to have the perceptual

delve into the project's requirements phase is asked to be familiar with the business involved in the project. You need to make sure that the way you communicate is effective, rather than whether it's UML or not, and if it's correctly expressed in UML.The customer is because he thinks you understand their needs and signs on the demand confirmation, not because your UML is accurate.Ensuring the effectiveness of every communication is the most important thing. Communication is not a simple matter

Decision Table Method: (strictest) Definition: A decision table is a table that lists all the combined values of all inputs as conditions and the corresponding output values. It is able to enumerate complex problems in all possible cases, concise and avoid omissions.　　Therefore, the decision table can be used to design a complete set of test cases.　　Structure: a decision table is usually composed

biggest, mainly to learn the author's experience, think selfAlready junior is nearing the end, programming ability is very poor, you may spend too little time, do not test will not spend too much time. The author university is not countedComputer professional, but the ability to program far more than the professional students, it is admirable, of course, the author is very devoted to programming, for this also paid aPrice, the junior senior had a lot of professional courses can not pass a few,

, between the different corners everywhere. All you need is to understand your situation, understand your role location, and understand the priorities of your communication with different roles. There will be no party a because you drag the project down just to make the project better and appreciate you, all you need to do is to understand where your character and other roles are focused, and communicate to make the project go more smoothly. In practice, the most valuable of the two quality is:
