Run a test load data from script calling processor

this is a modified version of the 'test load 20 records' ui action
create this as a copy
in the condition, add a condition to restrict it to the data source in question
in this example a file import

instead of having to redirect to the java processor, this can be done in script as follows:
(instance calls itself via httprequest to access the processor, this can enable users without permissions but who can see the UI action to perform a test load on the data source with the file attached)

 //--below is OOTB code, commented out but principles reused
/*var redirectStr = ""; // the URI
redirectStr += "import_source=data_source"; // this is a Data Source import
redirectStr += "&sysparm_data_source=" + current.sys_id; // the sys_id of this
redirectStr += "&sysparm_tablename=" + current.import_set_table_name; // always create the same test
redirectStr += "&sysparm_recreate_table=false"; // we dont want to overwrite existing
redirectStr += "&sysparm_tablelabel=" +;
redirectStr += "&create_new_module=ON";
redirectStr += "&sysparm_extends=sys_import_set_row"; // always extends this
redirectStr += "&selected_application=import_sets";
redirectStr += "&sysparm_default_state=test";
redirectStr += "&max_rows=2"; // change this number if you want more test rows*/

GlideRecord setValue

setValue(String name, Object value) Sets the specified field to the specified value. Normally a script would do a direct assignment, for example,  gr.category = value . However, if in a script the element name is a variable, then  gr.setValue(elementName, value)  can be used. When setting a value, ensure the data type of the field matches the data type of the value you enter. This method cannot be used on journal fields. If the value parameter is null, the record is not updated, and an error is not thrown!/api_doc?v=madrid&id=r_GlideRecord-setValue_String_Object
