In PHP, bcpow() function is used to raise an arbitrary precision base number to another exponent number. It takes two arbitrary precision numbers as strings and gives the base number raised to the power exponent after scaling the result to the listed precision.SyntaxString bcpow($base, $exponent, $scale)ParametersThe bcpow() function in PHP takes three different parameters: $base, $exponent and $scale.$base - It represents the base in which power will be raised and it is the string type parameter.$exponent - It represents the exponent and it is the string type parameter.$scale - It indicates the number of digits that appear after the decimal in ...

In PHP, bcadd() math function is used to add two arbitrary precision numbers. The bcadd() function takes two random precision numbers as strings and it returns the addition of the two numbers after scaling the result to an identified precision.Syntaxstring bcadd ( $num_str1, $num_str2, $scaleVal)ParametersThe bcadd() math function accepts three different parameters, $num_str1, $num_str2 and $scaleVal.$num_str1 - It represents the left operand and it is the string type parameter.$num_str2 - It represents the right operand and it is the string type parameter.$scaleVal - It is the optional parameter that is used to set the number of digits after the decimal place in the ...

An Entry widget is a basic one-line character widget that supports only single-line text input. An Entry widget can be defined by initializing the Entry(parent, width) constructor.To validate the Entry widget, we can use the get() method which results in the character entered in the Entry widget.Let us define an Entry widget that accepts single-line text input, and we will print the character that is input in the Entry widget.Example#Import the required Libraries from tkinter import * from tkinter import ttk #Create an instance of Tkinter frame win = Tk() #Set the geometry of Tkinter frame win.geometry("750x250") def get_content(): ...

We often use Open and Save Dialog. They are common across many applications and we already know how these dialogs work and behave. For instance, if we click on open, it will open a dialog to traverse the location of the file. Similarly, we have the Save Dialog.We can create these dialogs using Python tkFileDialog package. In order to work with the package, we have to import this in our environment.Type the following command to import the tkFileDialog package in the notebook, from tkinter.filedialog import asksaveasfileExampleIn this example, we will create an application that will save the file using the ...

Testing in a White BoxWhite Box Testing is a software examining technique that involves testing the product's underlying structure, design, and coding in order to verify input-output flow and improve design, usability, and security. White box testing is also known as Clear box testing, Open box testing, transparent box testing, Code-based testing, and Glass box testing since the code is visible to the testers.It's one of two components of the software testing approach known as Box Testing. Blackbox testing, on the other hand, entails testing from an external or end-user perspective. White box testing, on the other hand, is focused ... Read More
Thread testing is client-server-based testing to verify the primary function of an application. It is used to determine whether the application can run a specific task or thread or not.Why Thread Testing is important?Software is split into several threads with each thread running a specific task. When all components of the software are integrated, it is time for the developer to ensure the program runs as expected. For example, if it is a banking app, then the developer must make sure the app can execute all the transactions as per the client’s requirement. This is where thread testing comes to ... Read More
Recovery testing is system-based testing that ensures the system is capable of recovering from a failure. The process involves testing the system recovery process by voluntarily causing system failure. Besides testing the system fault-tolerance capabilities, the testing engineer also checks whether the system can resume itself within a pre-defined time. Recovery testing is an essential part of system testing that is a top requisite for mission-critical system-related such as defense systems, medical devices, banking, etc.Testing criteria of Recovery Testing process:Software or system is expected to recover from failures when −There is a loss of wireless signalThe external device doesn’t respondThe ...

Most companies, especially the one who develops small-sized applications are still ignorant to parallel testing. However, what these companies don't comprehend is the future is changing dynamically. Nowadays, users want an extensive range of functions in a single application. To cater to users' demands, you are bound to expand your applications in the coming times. When the stakes are high, and time-in-hand is low, then parallel testing is the answer.This article attempts to give you a fair idea about the importance of parallel testing, its implementation, and how it can change the landscape of testing solutions.What is Parallel Testing?Parallel testing ...

A software application contains an integration of various modules. Modules are programs written in a specific language consisting of subprograms, subroutines, functions, classes, and procedures. Module testing is a process where you need to test each unit of these modules to ensure they adhered to the best coding standards. Unless a module passes the testing phase, it cannot go for the application testing process.Module testing, aka component testing, helps to early detection of errors in application testing. This can be a massive relief for testers during the later stage of testing. Module testing is a gateway to parallel testing that ... Read More
Domain testing is a testing process where the software is tested to ensure it doesn't accept invalid or out-of-range values. The output is tested against a minimum number of inputs to see whether the system is accepting the input within the required range or not. The white box testing is a perfect example of domain testing.What is White Box Testing?In this process, testing engineers test the internal structure, coding, and software design, making sure it goes with the input-output flow. It also determines the design, usability, and overall security of the software. Since the code is visible to the testers, ... Read More
