The Java programming language (and its runtime) has undergone numerous changes since its release since its initial public release. These changes include: Changes in the Java programming language syntax and semantics Changes in the APIs provided by the Java standard class libraries. Changes in ...
Cucumber uses Gherkin syntax to describe your software's behaviors in structured natural language. As such Cucumber is not a test framework (a common misunderstanding), but a system documentation framework, not very different from others like Use Case Scenario. The common misunderstanding is due t...
Consider these two pieces of code: int a = 1000; int b = a + 1; and Integer a = 1000; Integer b = a + 1; Question: Which version is more efficient? Answer: The two versions look almost the identical, but the first version is a lot more efficient than the second one. The second version is...
You can organize the execution of your instrumented unit tests defining a Suite. /** * Runs all unit tests. */ @RunWith(Suite.class) @Suite.SuiteClasses({MyTest1.class , MyTest2.class, MyTest3.class}) public class AndroidTestSuite {} Then in AndroidStudio you can run...

Cassandra will not require users to login using the default configuration. Instead password-less, anonymous logins are permitted for anyone able to connect to the native_transport_port. This behaviour can be changed by editing the cassandra.yaml config to use a different authenticator: # Allow anon...
By default each user will be able to access all data in Cassandra. You'll have to configuring a different authorizer in your cassandra.yaml to grant individual object permissions to your users. # Grant all permissions to all users # authorizer: AllowAllAuthorizer # Use object permissions manage...
Private Sub Get_Last_Used_Row_Index() Dim wS As Worksheet Set wS = ThisWorkbook.Sheets("Sheet1") Debug.Print LastCol_1(wS) Debug.Print LastCol_0(wS) End Sub You can choose between 2 options, regarding if you want to know if there is no data in the worksheet :...
The simplest way to refer to a single cell on the current Excel worksheet is simply to enclose the A1 form of its reference in square brackets: [a3] = "Hello!" Note that square brackets are just convenient syntactic sugar for the Evaluate method of the Application object, so technicall...
To save a reference to a cell in a variable, you must use the Set syntax, for example: Dim R as Range Set R = ActiveSheet.Cells(3, 1) later... R.Font.Color = RGB(255, 0, 0) Why is the Set keyword required? Set tells Visual Basic that the value on the right hand side of the = is meant to be ...
NSDictionary can be enumerated using fast enumeration, just like other collection types: NSDictionary stockSymbolsDictionary = @{ @"AAPL": @"Apple", @"GOOGL": @"Alphabet", ...
The pattern (p1, p2) is strict in the outermost tuple constructor, which can lead to unexpected strictness behaviour. For example, the following expression diverges (using Data.Function.fix): fix $ \(x, y) -> (1, 2) since the match on (x, y) is strict in the tuple constructor. However, the fo...
