How to use the Random Module in Python ?
The random module provides access to functions that support many operations. Perhaps the most important thing is that it allows you to generate random numbers.
The Random module contains some very useful functions.
Randint => if we wanted a random integer .
Choice => Generate a random value from the sequence sequence.
Random => If you want a larger number, you can multiply it.
risk is the probabilty of any unwanted incidents. in software, using risk analysis at the beginning of a project highlights the potential problem areas when a test plan is created, risks involved in testing product are taken into consideration along with possibilty of damage they may cause to softare potential risks use of new hardware use of enw tech use of new automation tool sequence of code availability of test resources for app unavoidable risks time allocated for testing defect leakage due to complexity or size of app urgency from clients incomplete reqs risk magnitude indicators high - effect of risk very high and non-tolerable medium - tolerable but not desired low - tolerable risk identification business risk - risk coming from your company or customer not from project testing risk premature release risk software risk risk assessment effect cause likelihood three steps search for the risk analyze impact of each risk measures for risk identified Test Coverage test coverage is auseful tool for finding untested parts of a codebase higher coverage numbers don’t always mean good high nubmers are easy to reach with low quality testing tests can look for things that rarely go wron while distracting from testing things that really matter testing requires thoughtfulness if you are testing well 80-90% is great 100% is a little suspicious you are doing enough testing if the following is true: you rarely get bugs that escape into production you are rarely hesitant to change some code for fear it will cause production bugs if your tests are slowing you down or if simple code changes causes excessively long changes to tests, there may be a problem with the testa true value of coverage analysis is that it helps you find bits of code that aren’t being tested Big O In South Africa, the pigeon carrying the USB is O(1) while the data transfer time over the internet is O(N). Imagine mowing a 100x100 plot of land. It would be O(A) or area or O(S^2) or sides squared Big O rules different steps get added drop constants different inputs -> different variables drop non-dominant terms
