public PageReference sendEmail(){
        
        try{ 
            if(String.isBlank(toEmail)) {
                ApexPages.addMessage(new ApexPages.Message(ApexPages.severity.ERROR, 'Please enter To Address'));
                
                return null;
            }
            if(String.isBlank(subject)) {
                ApexPages.addMessage(new ApexPages.Message(ApexPages.severity.ERROR, 'Please enter Subject'));
                        return null;

The point is that as emails are not sent in tests asserting what has happened is awkward; one way around that is to create a class that the trigger uses to send:
Anjum Attar 26Anjum Attar 26
ApexPages.Message[] pageMessages = ApexPages.getMessages();
System.assertNotEquals(0, pageMessages.size()); // Check that the error message you are expecting is in pageMessages
Boolean messageFound = false;
for(ApexPages.Message message : pageMessages)
{
if(message.getSummary() == 'Your summary' && message.getDetail() == 'Your detail' && message.getSeverity() == ApexPages.Severity.YOUR_SEVERITY) {
messageFound = true;
}
}
System.assert(messageFound);
