Android automated test for activity destroyed and re-created -

-

We are trying to test the behavior of our application because it has different lifecycle states (active, paused, stopped, Destroyed) and then in those states, on the way back from the destroyed kingdom.

We have the problem that when instrumentation.callActivityOnCreate (testActivity, New Bundle)) is called,

04-16 15 : 40: 20.840 8989-898 / 9? E / AndroidRuntimeï¹ ??

Test activity

 Add a  setUp ()  to start your activity and conduct the exam to finish the  tearing ()  I'm destroying activities (I think this is what you want to do):  
  / ** * Example from Solo: providing ways to call the Android user interface Does. * * / Protected single single; / ** * Activity under trial * / Test activity activity; / * * (Non-JavaWadoc) * SEE android.test.ActivityInstrumentationTestCase2 # setUp () * / @ Override Protected Zero Set Up () Exception {activity = getActivity ()) throws; // If you are using robotium: single = new solo (getInstrumentation ()), getActivity ()); } @ Override Public Wide Tire Duown () throws exception {// Teardown ()) is run after a test case is over. // Finish Open Activitia () will terminate all the activities opened during the execution of the exam. Solo.finishOpenedActivities (); super.teardown (); }   
 Test if you receive an activity example at the beginning of each trial:  
  Public Zero TestVectorOntrusted and Starred () {// Valid The assertNotNull activity has been returned to ensure handles; }   
 When you want to test your ontoroy, try this code:  
  instrumentation.runOnMainSync {new Runnabel} {@Override Public Zero Run () {// to achieve activity to achieve activity = getActivity (); // Check that you are actually claiming a reference, the nautical (activity); // and here you are the activity instrumentation. Call ActiveAct (activity, new bundle));}});

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
