The unsung hero ‘grails interactive mode’"},"content":{"rendered":"

Of late, I have been thinking about the popularity of grails interactive mode amongst developers<\/a>. I found that though most of us are aware of this mode but we don’t use it as often, as it should be.<\/p>\n

Where should I use grails –interactive mode while developing in grails?<\/strong>
\nThe answer may vary from person to person and the level of expertise. For me, I found it amazing while running my tests and creating artifacts.<\/p>\n

I shall describe the advantages that I found with interactive mode while running Unit Tests. Let us take an example here:<\/p>\n

I have a class called PersonUtil which needs to be unit tested. I write a PersonUtilTests class for testing its functionality. In order to run this particular unit test, I can use the following command:<\/p>\n

grails test-app unit: PersonUtilTests<\/p>\n

This takes approximately 20 secs on an average to run on my machine with a decent configuration.<\/p>\n

Alternatively, We can run it in interactive mode. What we need to do is<\/p>\n

grails –interactive<\/p>\n

This shall bring the grails infrastructure up and make it just ready to run commands. It takes around 5 seconds.<\/p>\n

\n——————————————————–
\nInteractive mode ready. Enter a Grails command or type “exit” to quit interactive mode (hit ENTER to run the last command):<\/p>\n

Now, to test the app I can use the following command:<\/p>\n

——————————————————-
\nCommand TestApp completed in 2461ms
\n——————————————————–
\nInteractive mode ready. Enter a Grails command or type “exit” to quit interactive mode (hit ENTER to run the last command):
\ntest-app unit: PersonUtilTests<\/p>\n

It took 15 seconds to run this for first time.
\nFor subsequent runs, it took 2-4 seconds. Which is a clear advantage of 16 seconds for every run. These 16 seconds are no less than gem when you are in your “flow-state”( in concentration mode).<\/p>\n

While development, we make frequent changes to our code and therefore we need to run our unit tests multiple times. Every time I make a change and re run my unit test it takes 20 seconds through conventional grails test-app whereas it takes 3-4 seconds through interactive mode.<\/p>\n

Earlier, I used to get frustrated while waiting for test cases to execute. This waiting time is one of the biggest factor that drives us from doing Test Driven Development.<\/p>\n

Just in case you have not tried it. Please give it a shot. Believe me, it’s worth trying, you wont be disappointed!!!<\/p>\n","protected":false},"excerpt":{"rendered":"
