Controller Unit Test problem while params as a map

[Jet]

Hi All,

When running controller unit test. Setting the params individually like below works fine

controller.params.firstname = 'joe'
controller.params.lastname = 'blog'


However, if setting the params using a map like below:

controller.params = [firstname: 'joe', lastname: 'blog']

It would throw exceptions:

groovy.lang.ReadOnlyPropertyException: Cannot set readonly property: params for class:

any suggestions?

The obvious suggestion is to set the params individually.

Hi Burt,

Thanks for the reply.

It would be nice if the future version of grails can handle setting the params as a map in the test, otherwise setting those params can be tedious if the required property for the domain class is 10+.

However, if I do

println controller.params

It outputs a map.

The params are a read-only property, both during unit tests and normally.

The value is a GroovyPageAttributes, not a normal map (supports the "int(key)" and "boolean(key)" methods etc)

See

If you really must override it to a map of your own, you can do something like:

  controller.metaClass.getParams = {-> myMap}

You could also use a "with" block if you find writing "params." tedious, or possibly try params.putAll(myMap)?

Hi Jet,

To initialize multiple params in a test case, I generally do the following way which works better.

Map myParams = [firstname: 'joe', lastname: 'blog']

controller.params.putAll(myParams)

How about complex params like:

params.lead.id

which would fill a Lead attribute in a Purchase object?

Also, how do I create the Lead object the controller will find when I create the Purchase like

new Purchase(params)
