SIT and UAT are two types of testing methodologies, commonly used in software development. SIT (System Integration Testing) is used for testing the interfaces between different modules of the system such as software, hardware, etc. In contrast, UAT (User Acceptance Testing) is used to perform testing from the user end view to validate the product. In UAT, the system is tested for user’s requirements. Read this article to find out more about these two testing methodologies and how they are different. What is SIT? System Integration Testing (SIT) is a type of software testing which is performed in an ... Read More

In this post, we will understand the difference between test plan and test strategy −Test PlanIt is a document prepared for a software project that defines the approach, scope, and intensity required for software testing.It can be changed.It happens independently.It describes the details.It is only done by the test administrator or test manager.It is generally utilized at the project level.Its objective deals with how and when to test the product or system, and who would confirm it.Test StrategyIt is a set of instructions that explain the test design.They also help determine how the test has to be performed.It can’t be ...

The most basic difference between cohesion and coupling is that coupling is the representation of relationships between modules which uses the concept of inter−module, while cohesion is the intramodule representation of the relationship between modules. Read this article to find out more about Cohesion and Coupling and how these two important concepts are different from each other. What is Cohesion? In computer programming, cohesion is an indication that shows the relationship within modules. Cohesion provides the information about the functional strength of the modules. The greater the cohesion, the better will be the program design. Cohesion is basically the dependency ... Read More

Both EPROM and EEPROM are the types of ROM or Read Only Memory, but they are different from each other in many aspects that we will discuss in this article. Let's start with some basics of EPROM and EEPROM so that it becomes easier to understand the differences between them. What is EPROM? EPROM stands for Erasable Programmable Read Only Memory. EPROM is a modern version PROM (or Programmable Read Only Memory). EPROM provides the facility of erasing data stored on it. It uses ultraviolet rays (UV rays) to erase the content stored it. EPROM is built up of ... Read More

Both multiprogramming and multitasking are the concepts related to the operating systems of computer. It is not a good practice that keeping the CPU occupied for a single task only. Since, there is a considerable difference between the speeds of the CPU and other components of the computer system. This difference increases the CPU idle time and degrades its throughput. Therefore, to overcome this problem, several concepts such as multiprogramming, multitasking, multithreading, etc. have been developed to improve the CPU utilization. In this article, we will discuss the important differences between multiprogramming and multitasking. Let's start with some basics ... Read More

To retrieve the OS details of the Azure VM, we need to use the Get-AzVM command.ExampleGet-AzVM -VMName TestMachine2k16When you run the above command, it retrieves the VM TestMachine2k16 information and there is an OSType property which shows that if the VM’s OS is Linux or Windows, or any other type.But when you select the OSType, you won’t get anything. See below.ExamplePS C:\> Get-AzVM -VMName TestMachine2k16 | Select OStype OStype ------Because this property is a part of another property and hence can’t be accessed directly. When you expose the full properties of the VM, you will get the StorageProfile, which ... Read More

To delete the azure resource group using PowerShell, we need to use the Remove-AZResourceGroup command. But before using this command, make sure that no usable resources exist in the resource group that you want to delete.To check if the resources are available in the resource group, use the below command. Here we are using the TestRG resource group name.ExampleGet-AzResource -ResourceGroupName TestRGOnce you are confirmed that you need to delete the Resource Group then use the below command to delete the resource group.ExampleRemove-AzResourceGroup TestRG -Force -VerboseWhen you use the -Force parameter, you won’t be prompted for deletion confirmation.Read More

To export the azure VMs using PowerShell, we first need to get their desired properties. The cmdlet Get-AZVM will get all the VMs connected to the particular subscription. To export them to the CSV file we can use the below command.ExampleGet-AzVM | Export-Csv .\AZVMs.csv -NoTypeInformationOnce you run the above command, you will notice that you get all the properties of the VM, and sometimes they are not needed. To get the particular properties of the VM use the Select-Object (alias Select) command.ExampleGet-AzVM | Select Name, ResourceGroupName, Location, @{N='VMSize';E={$_.HardwareProfile.VmSize}} | Export-Csv .\AzureVms.csv -NoTypeInformationIf you want to export the VMs from a ...

Azure Resource Group is a container that stores the resources like Virtual Machines, Storage, IP addresses, etc. To create a new Azure Resource group, we need to use the New-AZResourceGroup command.To use this cmdlet, you first need to connect to the Azure account, and then if you want to create a resource group for the particular subscription you need to select that subscription.To create a new resource group, you need the location for the resource group. The below code will first connect to your Azure account, selects the Azure subscription, and then creates a new resource group.Example$ErrorActionPreference = "Stop" Connect-AzAccount Set-AzContext -SubscriptionName 'Enter your subscription name here' New-AzResourceGroup -Name 'TestRG' -Location 'Central US' -Tag @{'RG'='APP'}OutputResourceGroupName : TestRG ...

To get the available resources from the resource groups using PowerShell, we need to use the Get-AZResource command. Suppose we have the resource group name AnsibleTestRG and we need to retrieve the resources from the resource group, then we will use the below command.ExampleGet-AzResource -ResourceGroupName AnsibleTestRGTo filter the output, OutputGet-AzResource -ResourceGroupName AnsibleTestRG | Select Name, ResourceType, LocationOutputIf there are multiple resource groups in the particular subscription, we can use the below commands to export the resources from the resource group to the CSV file.Example$ErrorActionPreference = "Stop" try {     Connect-AZAccount     Set-AzContext -SubscriptionName 'Your Subscription Name'     $rgs = Get-AzResourceGroup ...
