isSorted

public S isSorted()

Verifies that the actual array is sorted into ascending order according to the natural ordering of its elements.

All array elements must be primitive or implement the Comparable interface and must be mutually comparable (that is, e1.compareTo(e2) must not throw a ClassCastException for any elements e1 and e2 in the array), examples :

• a array composed of {2, 4, 6} is ok because the element type is a primitive type.
• a array composed of {"a1", "a2", "a3"} is ok because the element type (String) is Comparable
• a array composed of Rectangle {r1, r2, r3} is NOT ok because Rectangle is not Comparable
• a array composed of {True, "abc", False} is NOT ok because elements are not mutually comparable (even though each element type implements Comparable)

Empty or one element arrays are considered sorted (unless the array element type is not Comparable).

Returns:

this assertion object.

isSortedAccordingTo

public S isSortedAccordingTo(Comparator<? super Double> comparator)

Verifies that the actual array is sorted according to the given comparator.
Empty arrays are considered sorted whatever the comparator is.
One element arrays are considered sorted if element is compatible with comparator, otherwise an AssertionError is thrown.

Parameters:

comparator - the Comparator used to compare array elements

Returns:

this assertion object.

usingElementComparator

public S usingElementComparator(Comparator<? super Double> customComparator)

Use given custom comparator instead of relying on actual type A equals method to compare group elements for incoming assertion checks.

Custom comparator is bound to assertion instance, meaning that if a new assertion is created, it will use default comparison strategy.

Examples :

 // compares invoices by payee 
 assertThat(invoiceList).usingComparator(invoicePayeeComparator).isEqualTo(expectedInvoiceList).
 
 // compares invoices by date, doesNotHaveDuplicates and contains both use the given invoice date comparator
 assertThat(invoiceList).usingComparator(invoiceDateComparator).doesNotHaveDuplicates().contains(may2010Invoice)
 
 // as assertThat(invoiceList) creates a new assertion, it falls back to standard comparison strategy 
 // based on Invoice's equal method to compare invoiceList elements to lowestInvoice.                                                      
 assertThat(invoiceList).contains(lowestInvoice).
 
 // standard comparison : the fellowshipOfTheRing includes Gandalf but not Sauron (believe me) ...
 assertThat(fellowshipOfTheRing).contains(gandalf)
                                .doesNotContain(sauron);
 
 // ... but if we compare only races, Sauron is in fellowshipOfTheRing because he's a Maia like Gandalf.
 assertThat(fellowshipOfTheRing).usingElementComparator(raceComparator)
                                .contains(sauron);
 

Parameters:

customComparator - the comparator to use for incoming assertion checks.

Returns:

this assertion object.

usingDefaultElementComparator

public S usingDefaultElementComparator()

Revert to standard comparison for incoming assertion group element checks.

This method should be used to disable a custom comparison strategy set by calling EnumerableAssert.usingElementComparator(Comparator).

Returns:

this assertion object.

containsExactly

public S containsExactly(double... values)

Verifies that the actual group contains only the given values and nothing else, in order.

Example :

 // assertion will pass
 assertThat(new double[] { 1.0, 2.0, 3.0 }).containsExactly(1.0, 2.0, 3.0);
 
 // assertion will fail as actual and expected orders differ.
 assertThat(new double[] { 1.0, 2.0, 3.0 }).containsExactly(2.0, 1.0, 3.0);
 

Parameters:

values - the given values.

Returns:

this assertion object.

Throws:

NullPointerException - if the given argument is null.

AssertionError - if the actual group is null.

AssertionError - if the actual group does not contain the given values with same order, i.e. the actual group contains some or none of the given values, or the actual group contains more values than the given ones or values are the same but the order is not.
