Assertion

Constructors

this

this(T _context)

Creates a instance of Assertion, wrapping a value or object

Members

Aliases

a

alias a = id

and

alias and = id

as

alias as = id

Identity function. Simply does nothing beyond making assertation more human friendly

be

alias be = id

Identity function. Simply does nothing beyond making assertation more human friendly

close

alias close = approxEqual

Alias to approxEqual

contain

alias contain = include

Asserts for an input range wrapped around an Assertion to contain/include a value.

have

alias have = id

of

alias of = id

to

alias to = id

Identity function. Simply does nothing beyond making assertation more human friendly

value

alias value = include

Asserts for an input range wrapped around an Assertion to contain/include a value.

which

alias which = id

Identity function. Simply does nothing beyond making assertation more human friendly

Functions

False

bool False(string file, size_t line)

Asserts for a boolean value to be equal to true.

Throw

void Throw(string file, size_t line)

Asserts whether a callable object wrapped around the assertion throws an exception of type T.

True

bool True(string file, size_t line)

Asserts for a boolean value to be equal to true.

approxEqual

T approxEqual(U other, U maxRelDiff, U maxAbsDiff, string file, size_t line)

Asserts that a float type is aproximated equal. Returns the valued wrapped around the assertion

biggerOrEqualThan

bool biggerOrEqualThan(U other, string file, size_t line)

Asserts if a value is bigger or equal than another value. Returns the result.

biggerThan

bool biggerThan(U other, string file, size_t line)

Asserts if a value is bigger than another value. Returns the result.

empty

bool empty(string file, size_t line)

Asserts for the .length property or function value to be equal to 0.

equal

T equal(U other, string file, size_t line)

Asserts for equality between two objects. Returns the value wrapped around the assertion.

exist

T exist(string file, size_t line)

Asserts whether a value exists - currently simply compares it with null, if it is a pointer, a class or a string. Returns the value wrapped around the assertion.

id

Assertion id()

Identity function. Simply does nothing beyond making assertation more human friendly

include

U include(U other, string file, size_t line)

Asserts for an input range wrapped around an Assertion to contain/include a value.

include

U include(U other, string file, size_t line)

Asserts for an input range wrapped around an Assertion to contain/include a value.

key

void key(U other, string file, size_t line)

Asserts for an associative array to have a key equal to other.

length

U length(U len, string file, size_t line)

Asserts for the .length property or function value to equal some value.

match

auto match(RegEx re, string file, size_t line)

auto match(U re, string file, size_t line)

Asserts for a string wrapped around the Assertion to match a regular expression.

not

Assertion not()

This function negates the wrapper assertion. With it, one can express fluent assertions without much effort.

smallerOrEqualThan

bool smallerOrEqualThan(U other, string file, size_t line)

Asserts if a value is smaller or euqal than another value. Returns the result.

smallerThan

bool smallerThan(U other, string file, size_t line)

Asserts if a value is smaller than another value. Returns the result.

sorted

bool sorted(string file, size_t line)

Asserts whether a forward range is sorted.
