海外TECH	DEV Community	Quality assurance fundamentals	https://dev.to/aatmaj/quality-assurance-fundamentals-19b8	Quality assurance fundamentals IntroductionPrevention is better than cure Not installing defects in the first place is better than debugging This can be achieved only through paying attention to quality assurance fundamentals from Day of your project Does poor quality hit After surveying projects it is found that poor quality is one of the most common reasons for schedule overruns Poor quality is the reason for half of the cancelled projects Here is how time and effort are lost due to bad quality The original effort spent designing and implementing the bad quality code or cut the corners short code is wasted because sooner or later the entire code will be thrown away By writing a bad code you are postponing the problem to later Time spent unit testing and debugging the code is down the drain At a later time of the project either the bad module will have to be replaced or worse scattered with patchworkAdditional time will be spent to strip the bad module out of the main code and modify it Additional testing and debugging time will be spent to ensure that the modified code still works Time will be spent in the design and implementation of the entire code due to changes in the bad module the new code which should have been designed as an integral part of the system has to be designed around the system All this could have been prevented if necessary steps would have been taken to ensure a good quality code from the start A stitch in time saves nine If you can prevent defects or detect and remove them early you can realize significant schedule benefits Studies have found out that reworking defective requirements design and code typically consumes of the total cost of software development Requirements defect that is left undetected until construction or maintenance will cost to times more than at requirements time If a defect is not detected in the early stages it becomes a time bomb later with times much more effort to fix The longer defects remain undetected the longer they take to fix Correct defects while they are young and easy to control Prevention is better than cure Every hour you spend on defect prevention will reduce your repair time by hours So the key to success is to implement practices that prevent the errors rather than fix them An error prone module is the one that is responsible for a majority of the bugs modules are responsible for of bugs Prevent the existence of such modules by using the practises given below Practises to prevent errorsTesting Testing is the black sheep of QA It is the messenger of disaster to the management But the best way to tackle it is to plan ahead for the bad news Deliver it as early as possible Unit testing where the developer checks their own code to verify if it works correctly has effectiveness in the range System testing in which an independent tester checks the system operation has an effectiveness of Technical walkthrough Walkthrough is a method by which two or more reviewers review technical work to improve quality Walkthroughs can find between per cent of errors in a program Such inspections are very effective when performed in the early stages and each hour spent in inspection saves hours of maintenance overhead Code reading In code reading two or more reviewers except for the author review the code This method is very effective and finds twice the number of defects per hour than testing Code review Code reviews are the most cost effective on a perdefect basis This is because they detect both the symptom of the defect and the underlying cause at the same time Testing detects only the symptom of the defect and not the cause and the developer still has to find the root cause of the defect They not only tend to find a higher percentage of defects but also provide a forum for developers to share their knowledge of best practices with each other which increases their rapid development over time Thus technical reviews are a critical component of any development effort that is trying to achieve the shortest possible schedule Notes and images from Rapid Development Taming Wild Software Schedules by Steve McConnell	2021-09-20 11:37:54

After years in jail for unlocking smartphonesThe mastermind behind a seven year scheme to illegally unlock AT amp T handsets has been sentenced to years in jail Muhammad Fahd unlocked phones for ineligible customers who still had to pay off the cost of their smartphone AT amp T says million handsets were unlocked in this manner and it lost around million because of the scheme Fahd contacted and subsequently bribed an AT amp T employee to help unlock devices until the company locked down the system Consequently Fahd commissioned malware to be installed on AT amp T s internal systems which captured data on both the company and its employees Fahd was indicted in arrested in Hong Kong a year later and extradited to the US in Perhaps the most staggering part of the story is the lengths Fahd went to keep the project going It s not clear if Fahd s malware put any customer data at risk but that a scheme like this was able to run for so long is troubling ーDan CooperUltra white paint could reduce the need for air conditioningSomeone stop Anish Kapoor from getting hold of this Purdue University John UnderwoodPretty much everyone knows you can make your house a lot cooler if you paint it white which is common practice in warmer countries Now however a team of scientists at Purdue University has cooked up the ultimate white paint which they claim works so well it could eliminate the need for air conditioning The covering supposedly reflects percent of all solar radiation theoretically leaving the surface cooler than the surrounding environment If it works and it s implemented properly it could reduce the global energy bill by quite a figure Continue Reading Netflix and Apple TV clean up at the Emmys with The Crown and Ted Lasso HBO is the only traditional
