If you’re not familiar with test, it’s a tool for automated testing of computer software. Automated tests are programmed to run through the features and functions that make up an application without any manual input from humans. Test is still in early development but has made some serious strides recently with its platform-agnostic framework
Test is a command-line tool that allows users to measure the speed of their computer or network connection. The “test speed” command will provide you with the current speed of your system.
PowerShell Test-Connection is the cmdlet of the day for today. The cmdlet Test-Connection, as the name suggests, checks your network connection. Consider Test-Connection to be PowerShell’s version of the ubiquitous ping command. Despite the fact that they both use ICMP, you’ll see that the two approaches are somewhat different beneath the hood.
It’s easy to use this cmdlet. Simply specifying a ComputerName argument causes four ICMP queries to be sent to the target host.
PS> Test-Connection -ComputerName google.com Source Destination IPV4Address IPV6Address Bytes Time(ms) —— ———– ———– ———– —– ——– MACWINVM google.com 172.217.0.14 2607:f8b0:4009:80c::200e 32 47 MACWINVM google.com 172.217.0.14 2607:f8b0:4009:80c::200e 32 90 MACWINVM google.com 172.217.0.14 2607:f8b0:4009:80c::200e 32 88 MACWINVM google.com 172.217.0.14 2607:f8b0:4009:80c::200e 32 205
On the surface, this output resembles that of ping.exe, but Powershell test-connection sends the ICMP request in a slightly different way. Unlike ping.exe, Test-Connection sends the ICMP request via the Win32 PingStatus WMI class on the local machine. If you’re going to use the local WMI repository, make sure it’s up to date and healthy, else Test-Connection won’t function.
Object Output from PowerShell Test-Connection
Also, as is typical with PowerShell, this cmdlet doesn’t just return what appears in the console right away. We observe interesting items from which we may learn more.
You can see that I’ve gotten a lot more valuable information if I assign the output to a variable and then look at the attributes.
PS> $pingResults | Get-Member TypeName: System.Management.ManagementObject#rootcimv2Win32_PingStatus Name MemberType Definition —- ———- ———- PSComputerName AliasProperty PSComputerName = __SERVER Address Property string Address {get;set;} BufferSize Property uint32 BufferSize {get;set;} NoFragmentation Property bool NoFragmentation {get;set;} PrimaryAddressResolutionStatus Property uint32 PrimaryAddressResolutionStatus {get;set;} ProtocolAddress Property string ProtocolAddress {get;set;} ProtocolAddressResolved Property string ProtocolAddressResolved {get;set;} RecordRoute Property uint32 RecordRoute {get;set;} ReplyInconsistency Property bool ReplyInconsistency {get;set;} ReplySize Property uint32 ReplySize {get;set;} ResolveAddressNames Property bool ResolveAddressNames {get;set;} ResponseTime Property uint32 ResponseTime {get;set;} ResponseTimeToLive Property uint32 ResponseTimeToLive {get;set;} RouteRecord Property string[] RouteRecord {get;set;} RouteRecordResolved Property string[] RouteRecordResolved {get;set;} SourceRoute Property string SourceRoute {get;set;} SourceRouteType Property uint32 SourceRouteType {get;set;} StatusCode Property uint32 StatusCode {get;set;} Timeout Property uint32 Timeout {get;set;} TimeStampRecord Property uint32[] TimeStampRecord {get;set;} TimeStampRecordAddress Property string[] TimeStampRecordAddress {get;set;} TimeStampRecordAddressResolved Property string[] TimeStampRecordAddressResolved {get;set;} TimestampRoute Property uint32 TimestampRoute {get;set;} <SNIP>
Test-Connection will utilize DCOM to authenticate to remote hosts if you’re testing internal hosts. It will employ Packet level DCOM authentication by default, however the authentication type may be changed at any time using the DcomAuthentication argument.
Working in the Background
This cmdlet may also be set to run in the background. If you have a lot of distant computers to ping and don’t want to wait long for ones that will ultimately time out, you may send it to a background task.
PowerShell remoting must be enabled on both the local and distant computers, according to the PowerShell support for Powershell test-connections, however this is not the case. I’m trying google.com, as you can see below, and the command still works well.
Google.com -ComputerName Test-Connection -AsJob
Get-A-Job | Get-A-Job
Maintaining Simplicity
Finally, the Quiet option may be used to get a binary yes/no response as to whether or not a machine is responding. Using Quiet and a Count of 1 to compel Test-Connection to submit a single ICMP request is a common string I always use to quickly test whether a server is available or not.
PS> Test-Connection -ComputerName google.com -Quiet -Count 1 True
This concludes our cmdlet of the day! We covered the most of what PowerShell test-connection can perform, but for a complete analysis, go to the PowerShell help page or the Microsoft website.
The “test assessment” is an online test that you can take to assess your knowledge on a specific topic.
Frequently Asked Questions
What do you mean by a test?
A: A test would be a small section of the song that you could use to judge if the tempo, dynamics and rest periods are similar enough for your taste. If it doesnt sound like what you want, then theres some work to do before moving on to mastering.
What is a test in research?
A: A test is a procedure that is used to evaluate the validity of an idea or hypothesis. It often consists of administering a questionnaire, and sometimes one-off experiments are also included.
What is test example?
A: Test example is just a word. Its used to refer to an individual or group of individuals who are being tested for some purpose, such as the test examples given in a multiple choice question.
