Functional tests are best described as tests for your user stories. If you've dealt with user stories before they normally follow the following pattern: As a [role], I want to [desire], so that [benefit/desired outcome] For the following examples we'll use this user story as an example: As a Du...

The predicate function matches can be used to evaluate strings on the fly without use of any object declarations. IF matches( val = 'Not a hex string' regex = '[0-9a-f]*' ). cl_demo_output=>display( 'This will not display' ). ELSEIF matches( val = '6c6f7665' reg...

As already pointed out in other pitfalls, catching all exceptions by using try { // Some code } catch (Exception) { // Some error handling } Comes with a lot of different problems. But one perticular problem is that it can lead to deadlocks as it breaks the interrupt system when writ...

Solr is a standalone enterprise search server with a REST-like API. You put documents in it (called "indexing") via JSON, XML, CSV or binary over HTTP. You query it via HTTP GET and receive JSON, XML, CSV or binary results. Solr uses the Lucene search library and extends it. Here are som...

This example finds a point on a bezier or cubic curve at position where position is he unit distance on the curve 0 <= position <= 1. The position is clamped to the range thus if values < 0 or > 1 are passed they will be set 0,1 respectively. Pass the function 6 coordinates for quadrati...

Unlike most other JavaScript objects, symbols are not automatically converted into a string when performing concatenation. let apple = Symbol('Apple') + ''; // throws TypeError! Instead, they have to be explicitly converted into a string when necessary, (for example, to get a textual description...

The | can be used to have a single case statement match against multiple inputs to yield the same result: def f(str: String): String = str match { case "foo" | "bar" => "Matched!" case _ => "No match." } f("foo") // res0: String = M...

Given the following List of tuples: val pastries = List(("Chocolate Cupcake", 2.50), ("Vanilla Cupcake", 2.25), ("Plain Muffin", 3.25)) Pattern matching can be used to handle each element differently: pastries foreach { pa...

This is an example of an implementation of the identity monad in JavaScript, and could serve as a starting point to create other monads. Based on the conference by Douglas Crockford on monads and gonads Using this approach reusing your functions will be easier because of the flexibility this monad...

We're going to use the expression tree API to create a CalculateSalesTax tree. In plain English, here's a summary of the steps it takes to create the tree. Check if the product is taxable If it is, multiply the line total by the applicable tax rate and return that amount Otherwise return 0 ...

Sometimes we want to look at what is sent and received in the SOAP request. The following methods will return the XML in the request and response: SoapClient::__getLastRequest() SoapClient::__getLastRequestHeaders() SoapClient::__getLastResponse() SoapClient::__getLastResponseHeaders() For ex...

When static_cast is used to convert T D::* to T B::*, the member pointed to must belong to a class that is a base class or derived class of B. Otherwise the behavior is undefined. See Derived to base conversion for pointers to members

For the built-in shift operator, the right operand must be nonnegative and strictly less than the bit width of the promoted left operand. Otherwise, the behavior is undefined. const int a = 42; const int b = a << -1; // UB const int c = a << 0; // ok const int d = a << 32; // ...

C++11 Example from the Standard, [dcl.attr.noreturn]: [[ noreturn ]] void f() { throw "error"; // OK } [[ noreturn ]] void q(int i) { // behavior is undefined if called with an argument <= 0 if (i > 0) throw "positive"; }

Example from the Standard, [temp.inst]/17: template<class T> class X { X<T>* p; // OK X<T*> a; // implicit generation of X<T> requires // the implicit instantiation of X<T*> which requires // the implicit instantiation of X<T**&...
