Automating batch files and powershell script execution - powershell

Question

The goal is to automate the execution of 3 files:
A batch file that runs a selenium webdriver automated test suite.
Another batch file that generates a reports for the tests run in step 1.
A PowerShell script that attaches the reports and sends an email.
How can I automate the execution of these 3 files so that upon running a command or executing a file, all 3 are executed?
This is how my PowerShell looks like:
$Username = "";
$Password = "";
function Send-ToEmail([string]$email, [string]$attachmentpath) {
$message = New-Object Net.Mail.MailMessage;
$message.From = "c#c.com";
$message.To.Add($email);
$message.Subject = "abc";
$message.Body = "abc";
$attachment1 = New-Object Net.Mail.Attachment($attachmentpath);
$message.Attachments.Add($attachment1);
$smtp = New-Object Net.Mail.SmtpClient("build3", "25");
$smtp.EnableSSL = $false;
$smtp.Credentials = New-Object System.Net.NetworkCredential($Username, $Password);
$smtp.Send($message);
Write-Host $smtp.EnableSSL;
Write-Host "Mail Sent";
}
Send-ToEmail -email "a#a.com" -attachmentpath "C:\file1";
Send-ToEmail -email "b#b.com" -attachmentpath "C:\file1";
This is what the first batch file looks like:
FOR /F "TOKENS=2 eol=/ DELIMS=/ " %%A IN ('DATE/T') DO SET dd=%%A
FOR /F "TOKENS=2,3 eol=/ DELIMS=/ " %%A IN ('DATE/T') DO SET mm=%%B
FOR /F "TOKENS=2,3,4 eol=/ DELIMS=/ " %%A IN ('DATE/T') DO SET yyyy=%%C
SET todaysdate=%yyyy%%mm%%dd%
start /d "nunitPATH" nunit3-console.exe "seleniumtestsuite dll PATH" --where:cat==SignUp --result="xmlreportPATH"
This is what the second batch file looks like:
start /d "exeFilePATH" ReportUnit.exe "folderPATH"

Answer 1

Simply write a batch script that runs
call script1.bat
call script2.bat
D:\path\to\powershell.exe -File script3.ps1
If you need async:
start script1.bat
start script2.bat
start "" "D:\path\to\powershell.exe" "-File" "script3.ps1"
Note the pair of double quotes before powershell.exe path.
Note that this assumes your device has at least powershell v2
