Mockito verify input parameter was called with a given value

Edit 23.04.2018
According to this issue, Mockito cannot capture var-args still.

There is a very easy way to verify a method has been called with the right parameter in Mockito. All you need to do is use captors, to capture the actual argument. Here is how you can use them:

 
ArgumentCaptor argument = ArgumentCaptor.forClass(RuleEntity.class);
 verify(mRulesRepository).createRule(argument.capture());
 assertEquals(1,argument.getValue().getRules().get(0).getTriggers().size())

Simple it is, just a quick reminder for starters.

Ubuntu – Alt + Shift + any key switches the language and does not work

I faced this bug in Ubuntu 18.04. When I used Alt + Shift + 7 inside Webstorm which is the command for Find Usages, it actually changed the language because the command included Alt + Shift (I previously set this by using Gnome Tweak Tool). Here is a bug related to this in Launchpad.

Installing Grub fails on Ubuntu 16.04

I got this nasty error when it came to having a fresh install of Ubuntu 16.04. It says that GRUB cannot be installed on /target device. In order to fix this you need to:

  1. Create a partition around 300 mbs
  2. Use the FAT32 format and target it as EFI partition
  3. Choose that the GRUB installer should be installed on this 300 mbs partition

Then the installation should finish succesfully without any errors.

Add application to launcher in Ubuntu 16.04

Just use a program called alacarte:

sudo apt-get install alacarte

Click on the New Item button, write the command & name of the app, choose a logo if you want and you will see it appearing shortly in the Unity launcher by typing the name. Otherwise, you will have to create a *.desktop file and add it to .local/share/applications which I couldn’t make it work after spending a couple of hours.

Test push notifications on Android without a server

How I used to do it

The biggest problem I have with push notifications and especially GCM is testing them. Every time I want to test a notification, I would create a sample project in Google Developers Console, use the JSON there and then use Postman to send HTTP requests to the device, after obtaining the device registration id and the token for the project.

EditText in CollapsingToolbar with NestedScrollView won’t scroll when the keyboard is open

The problem

What we currently have

  • CoordinatorLayout with CollapsingToolbar inside
  • The CollapsingToolbar has an ordinary Toolbar inside that displays text
  • A NestedScrollView with multiple EditText fields inside of it which actually pushes the CollapsingToolbar to collapse when you try to enter something in the EditText
