What is Security testing? Security testing is a process to determine that an information system protects data and maintains functionality as intended. It is the process that determines that confidential data stays confidential and users can perform only those tasks…
Why is testing necessary? Testing is necessary because we all make mistakes. Some of those mistakes are unimportant, but some of them are expensive or dangerous. We need to check everything and anything we produce because things can always go…
Passive Components RESISTORS To oppose the flow of electrons ( current). The symbols are shown below. Resistance is measured in units called “Ohm”. 1000 ohms is shown as 1k ohm (103 ohm) and 1000 k ohm is shown as M.ohms…

No Sound from Ubuntu linux or Mint Searched google for possible answer to the problem but solution mentioned was not sufficient to solve my issues. I wasted couple of weekends resolving this issue.Finally I solved by removing PulseAudio and ALSA…
Over the years I found that members of software development teams, developers, testers, administrators and managers alike have an insufficient grasp on how to apply mathematics or interpret statistical data on the job. As performance testers, we must know and…
How to calculate the cost of test automation: Cost of test automation = Cost of tool(s) + Labor costs of script creation + Labor costs of script maintenance If a test script will be run every week for the…
