how to generate emailable format execution report using testng-results.xml

Question

I just want to create an emailable template execution report by using the testng-results.xml files through JAVA or testng listeners. I have existing testng-results.xml file which I need to make it as emailable reports. Is there any way to do that. I just need some input and ideas to kick start this activity.

Any leads.

Answer 1

Use XSLT template , the most efficient and easy way to generate to any report format from xml.

In my project, we are generating different category of html reports from testng-results.xml for fast regression analysis. Also we had generated json report using xslt from testng-results.xml to see aggregate result.

We use gradle build tool to run xslt and generate report after completion of test like,

configurations{ xslt }

dependencies {
    xslt    'net.sf.saxon:saxon:8.7'
}
task generateReport << {
    File reportDir=new File("${projectDir}/HTML_Reports")
    if(reportDir.exists()){
        reportDir.deleteDir()
    }
    reportDir.mkdir()
    ant.xslt(in: "${testReportDir.absolutePath}/test/testng-results.xml",
             style: "${projectDir.absolutePath}/src/test/resources/xslt_config/emailablereport.xsl",
             out: "${reportDir.absolutePath}/index.html",
             classpath: configurations.xslt.asPath) {
            param(name: 'paramXSLT.environment', expression: "${env}")
        }

You can also run xsl in maven using this plugin
