There was a time where I saw some tests which my colleagues made where the file name in the test folder would be: “users.spec.coffee”. So “spec” is short of specification and it is a totally different way of how we think about tests.

Using card.io from the source and not from Maven requires you to have the latest Android NDK with which the project will be built. But compiling it with the latest NDK introduces a bug which prevents the library from supporting several phones like Samsung S5, Honor 7 and others.

given(mUserRepo.getUser(anyString(). any())).willReturn(new User());
And what will happen if
mUserRepo.getUser(null);
UserRepo is called with null? Well, the matcher doesn’t work and the test fails. anyString() does not work with null values. If you pass null to a mocked service then use any() as a matcher.
It is so easy guys, just don’t forget that DataBinding creates a field called context which you can access by default in your XML file. So you can write something like this:
<data>
<variable name="name" type="String"/>
</data>
<layout>
<TextView
app:text="@{StringUtils.format(context, name)}" />
</layout>
And it will be just fine. You have the context from the parent view. Check it HERE.
There is a very simple solution in Android if you want to have space between components. You can always set margins but you can also use the Space class. You can use it like this:
<Space android:layout_width="1dp" android:layout_height="30dp"/>
Situation is like this:
I had to implement a feature toggle recently.
I will keep it short. You have to add a new feature to your product, but you want that feature to be available only for certain type of users. What you do? Well, you just make an if check to see the user can see this feature and then you toggle it for him. Here is a sample check:
if(ToggleRouter.isEnabled("comments")) {
// Display the feature to the user
}

You have probably heard this form me. I am working on a Sails js project and I wanted to implement a simple role management. That means that I have several routes like: “/admin”, “/login”, “/users” and I want the admin route to be accessed only from admins, login to be accessed from admin and users and the users route to be accessed from only the users.
