How do you conduct function Testing?
Functional TestingAll the user requirements as specified by the business should be well tested as a part of functional testing. Functional Testing demands Testing in the environment similar to that of client’s requirement. All the boundary conditions, negative scenario are accounted for. Each functionality of the application should be working well with minimal probability of any bug.Objective of Functional TestingThe basic requirement which is expected out of a well running application should be tested. The UI should be user friendly and easy to navigate. Error messages should pop-up in case any unwanted entry is entered.A bug free application with the ...
Read MoreWhat is the role of test automation in functional testing?
To ensure smooth, speedy and effective testing and delivery of a project, automation plays a crucial role. It becomes very essential in this digital business that continuous testing and delivery are ensured.Automation requires tools which control and compare the actual and the expected results. Repetitive execution as a part of Regression is also considered when Automation is talked about.While handling a huge project, automation plays a key role where few areas needs to be tested again and again in periodic interval. End-to-end testing result ensure the robust working of the application.When Automation is considers, it becomes very significant to identify ...
Read MoreWhen Should I use Selenium Grid?
IntroductionAmong the four flavors of Selenium, Selenium Grid is one such flavor. The facility to run multiple tests on multiple machines, on multiple browsers simultaneously is made possible by Selenium Grid. It also allows running test cases on multiple browsers in parallel.Selenium Grid has 2 versions- older Grid 1 and older Grid 2. Old Grid 1 is obsolete now, hence Grid 2 is used.Selenium 2 is bundled with Selenium Server jar file. There is no need to install Apache Ant unlike Grid 1.How it worksSelenium Grid consists of hub and multiple nodes. Test runs on single machine called Hub and ...
Read MoreProgram to Divide two 8 Bit numbers in 8051 Microprocessor
Here we will see the division operation. This operation will be used to divide two 8-bit numbers using this 8051 microcontroller. The register A and B will be used in this operation. No other registers can be used for division. The result of the division has two parts. The quotient part and the remainder part. Register A will hold Quotient, and register B will hold Remainder.We are taking two number 0EH and 03H at location 20H and 21H, After dividing the result will be stored at location 30H and 31H.AddressValue …20H0EH21H03H …30H00H31H00H …Program MOV R0, #20H ; set source address 20H ...
Read MoreProgram to Multiply two 8 Bit numbers in 8051 Microprocessor
Here we will see how to multiply two 8-bit numbers using this 8051 microcontroller. The register A and B will be used for multiplication. No other registers can be used for multiplication. The result of the multiplication may exceed the 8-bit size. So the higher order byte is stored at register B, and lower order byte will be in the Accumulator A after multiplication.We are taking two number FFH and FFH at location 20H and 21H, After multiplying the result will be stored at location 30H and 31H.AddressValue …20HFFH21HFFH …30H00H31H00H …Program MOV R0, #20H ; set source address 20H to R0 ...
Read MoreProgram to Subtract two 8 Bit numbers in 8051 Microprocessor
Now, in this section we will see how to subtract two 8-bit numbers using 8051 microcontroller. The register A (Accumulator) is used as one operand in the operations. There are seven registers R0 – R7 in different register banks. We can use any of them as second operand.We are taking two number 73H and BDH at location 20H and 21H, After subtracting the result will be stored at location 30H and 31H.AddressValue …20H73H21HBDH …30H00H31H00H …Program MOV R0, #20H ; set source address 20H to R0 MOV R1, #30H ; set destination address 30H to R1 ...
Read MoreProgram to Divide two 8 Bit numbers in 8085 Microprocessor
Here we will see 8085 program. This program will divide two 8-bit numbers using 8085 microprocessor.Problem Statement −Write an 8085 Assembly language program to divide two 8-bit numbers and store the result at locations 8020H and 8021H.Discussion −The 8085 has no division operation. To get the result of division, we should use the repetitive subtraction method.By using this program, we will get the quotient and the remainder. 8020H will hold the quotient, and 8021H will hold remainder.We are saving the data at location 8000H and 8001H. The result is storing at location 8050H and 8051H.InputThe Dividend: 0EHThe Divisor 04HThe Quotient will be ...
Read MoreProgram to Subtract two 8 Bit numbers in 8085 Microprocessor
Here we will see one 8085 program. In this program we will see how to subtract two 8-bit numbers.Problem Statement −Write an 8085 Assembly language program to subtract two 8-bit numbers and store the result at locations 8050H and 8051H.Discussion −In 8085, the SUB instruction is used 2’s complemented method for subtraction. When the first operand is larger, the result will be positive. It will not enable the carry flag after completing the subtraction. When the result is negative, then the result will be in 2’s complemented form and carry flag will be enabled.We are using two numbers at location 8000H and ...

Here we will see one 8085 assembly language program. In this program we will see how to add two 8-bit numbers.Problem Statement −Write an 8085 Assembly language program to add two 8-bit numbers and store the result at locations 8050H and 8051H.Discussion −To perform this task, we are using the ADD operation of 8085 Microprocessor. When the result of addition is 1-byte result, then the carry flag will not be enabled. When the result is exceeding the 1-byte range, then the carry flag will be 1We are using two numbers at location 8000H and 8001H. When the numbers are 6CH and 24H, ...
