This is a fork of grails greenmail plugin for grails 3.
Add a dependency for the plugin in build.gradle
:
dependencies {
compile 'org.grails.plugins:greenmail:2.0.0.RC2'
}
Provides a wrapper around GreenMail and provides a view that displays sent
messages - useful for testing application in the development
or test
environments.
grails install-plugin greenmail
The plugin assumes that you have some sort of Java mail provider installed (for instance the Grails mail plugin). You need to define a SMTP port for the mock Greenmail SMTP server to start with. Using the Grails Mail plugin, this is as simple as defining the grails.mail.port
property in Config.groovy
, like this (see the first line in the development
and test
blocks):
environments {
production {
grails.serverURL = "http://www.changeme.com"
}
development {
grails.mail.port = com.icegreen.greenmail.util.ServerSetupTest.SMTP.port
grails.serverURL = "http://localhost:8080/${appName}"
}
test {
grails.mail.port = com.icegreen.greenmail.util.ServerSetupTest.SMTP.port
grails.serverURL = "http://localhost:8080/${appName}"
}
}
You can also completely disable the plugin by using the config setting grails.plugin.greenmail.disabled = true
. For example, to disable greenmail in production:
environments {
production {
grails.plugin.greenmail.disabled=true
}
}
If you need to change the default listening port (1025) you can use the grails.plugin.greenmail.ports.smtp
configuration variable. For example:
environments {
test {
grails.plugin.greenmail.ports.smtp = 2025
}
}
The plugin can be used to capture email messages during integration tests. For example:
import com.icegreen.greenmail.util.*
class GreenmailTests extends GroovyTestCase {
def mailService
def greenMail
void testSendMail() {
Map mail = [message:'hello world', from:'[email protected]', to:'[email protected]', subject:'subject']
mailService.sendMail {
to mail.to
from mail.from
subject mail.subject
body mail.message
}
assertEquals(1, greenMail.getReceivedMessages().length)
def message = greenMail.getReceivedMessages()[0]
assertEquals(mail.message, GreenMailUtil.getBody(message))
assertEquals(mail.from, GreenMailUtil.getAddressList(message.from))
assertEquals(mail.subject, message.subject)
}
void tearDown() {
greenMail.deleteAllMessages()
}
}
The plugin adds a deleteAllMessages()
convenience method to the greenMail
bean that deletes all received messages.
The plugin provides a controller and view to show messages that are sent
from the application. Simply browse to http://localhost:8080/greenmail and it will show a list of messages sent. You can click on the show
link to view the raw message.
This is a fully functional plugin, though there are some features that I think would be worth adding. Contributions and patches are welcome!
- Messages sent by the Grails Mail plugin have duplicate "TO:" fields in the raw message and in the address list, for instance if the recipient is [email protected], then that email address is listed twice when you retrieve the address list for RecipientType.TO (e.g. GreenMailUtil.getAddressList(message.getRecipients(javax.mail.Message.RecipientType.TO))
- Ability to view HTML email messages as they appear in a mail client rather than as RAW message.
