We do some testing involving serial communications with a device. Right now, we are using Tera Term to communicate. I'd like to bypass the terminal program entirely and just have TestComplete send strings to the device and receive responses. Does anyone have any sample code of how I can do this?
Hi rlent
The below smartbear link might be of some help.
Below is the sample VB Script code which is taken from the link
Sub Test
Dim Port, i, s
Set Port = dotNET.System_IO_Ports.SerialPort.zctor_4("COM1", 9600)
Port.Open
' Writing data to the port
Port.Write "A " & Chr(27)
' Waiting for response
aqUtils.Delay 1000
' Processing response
If Port.BytesToRead <> 0 Then
s = Port.ReadExisting
Log.Message s
Else
Log.Warning "No data"
End If
Port.Close
End Sub
Hi,
I am trying to send data to a COM port and found the following solution in TestComplete website
https://support.smartbear.com/testcomplete/docs/scripting/working-with/com-ports.html
I used the following solution as described in the web page (Python). However, when I run my test
it gave an error Permission denied. Any idea on how to solve this error?
def TestCOMPort():
ForWriting = 2;
TriStateFalse = 0;
fso = Sys.OleObject['Scripting.FileSystemObject']
f = fso.OpenTextFile("COM1:", ForWriting, False, TriStateFalse)
# Write data to the port
f.Write("A")
f.Write(" ")
f.Write("\x1B")
f.Close()
Hi,
a) What line of code produces the error?
b) Does this help: https://stackoverflow.com/questions/1153547/access-to-the-port-com1-is-denied ?
Hi,
I don't have ready code samples, but I am pretty sure such communication is possible with the help of the CLR Bridge from TestComplete.
Try to search for C# / VB.Net code samples and port them to your scripting language (e.g. http://stackoverflow.com/questions/1243070/how-to-read-and-write-from-the-serial-port and http://stackoverflow.com/questions/13754694/what-is-the-correct-way-to-read-a-serial-port-using-net-framework).
Code from https://support.smartbear.com/viewarticle/9003/ section can be used as an example.
In the worst case you may create a regular .Net class library that implements port communication that you need (with the assistance from your developers?) and just call methods of this library from your TestComplete code via the mentioned CLR Bridge.
Hi,
Wanted to know how would you read the response? Will you be reading the response from the port directly or is there any change/ data coming to your application UI
