Page Object is a Design Pattern which has become popular in test automation for enhancing test maintenance and reducing code duplication. A page object is an object-oriented class that serves as an interface to a page of your Application under test.…
Resistance colour codes Below is the table containing resistance colour codes. Each color band represents a number and the order of the color band will represent a number value. The first 2 color bands indicate a number. The 3rd color…
To Locate UI elements in Selenium each of the language bindings expose a “Find Element” and “Find Elements” method. The first returns a WebElement object otherwise it throws an exception. The latter returns a list of WebElements, it can return…
Difference between “AndWait” and the “waitFor” Commands The difference between a command and its AndWait alternative is that the regular command (e.g. click) will do the action and continue with the following command as fast as it can, while the AndWait alternative (e.g. clickAndWait) tells Selenium…
Sanity testing and Smoke testing. What is the difference? For last 10 years I have answered this question justifying the answer which I read in book. This is also one of my question in interviews. It is such a question which…
RESISTOR COMBINATIONS When we do not get specific resistor values we have to either use variable resistors such as potentiometers or presets to obtain such precise values. Pots are too expensive to use forevery case. Another scheme is to combine…
Today LED has become an integral part of consumer electronics. LED TV, LED Display, LED Lights and so on. These are becoming very popular because of there low power consumption. What is LED? LED stands for Light emitting diode. A…
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…
Introduction Electronic component can be divided into 2 types: Active and Passive components Resistors and Capacitors etc. are known as passive components because they can only attenuate the electrical voltage and signals and cannot amplify. Devices like transistors and operational amplifier(op…
