  • Automating SVN Check-Ins And Building A Project Via JenkinsFeb 05, 2018. A few weeks back, while sitting with my team, I learned that they run a Jenkins job which has to execute the automation scripts using the robot framework, daily around 1:00 a.m. The primary purpose of the job is to place all the necessary files and folders over the node machine of Jenkins (after copying them from the machine pointed as master on Jenkins), execute those scripts accordingly, generate the reports, and finally copy the output files back to the master machine to analyze the logs for the overall reporting and analysis purposes. This whole efficient job starts with a slack manual step which was enough to tag this activity 'not fully automated' because they had to place the updated work regularly on the specified path over the master machine before leaving the office (this includes taking the updated code, files, and automation scripts, building the project to take the DLLs etc.). This may sound tedious but more than that, there is no sense to do it manually.

  • Basics Of Angular And Its Versions - Part TwoJan 15, 2018. Module is nothing but a package like a package in Java, a namespace in C# and like a header-file in C / C++.
