В этой статье показано, как смоделировать инфраструктуру JMS с помощью MockRunner и протестировать ее с помощью Spring. Его легко протестировать без инфраструктуры JMS, такой как Active MQ, OpenJMS и т. Д. Инфраструктура Mockrunner упрощает JMS, пока вы внедряете JMS или пытаетесь воссоздать производственную проблему без зависимости.

 В этой статье я покажу, как создать простой слушатель текстовых сообщений и отправить сообщение в очередь. 

1. Требования:

• специалист 
• весна 
• MockRunner 
• STS IDE
