contains

infix fun <T : CharSequence> Expect<T>.contains(o: o): CharSequenceContains.EntryPointStep<T, NoOpSearchBehaviour> (source)

Starts a sophisticated contains assertion building process based on this Expect.

expect("ABC") contains o exactly 1 value "A"

expect("ABBC") contains o atLeast 2 value "B"

fails {
    expect("AAAAAA") contains o atMost 3 value "A"
}

Parameters

o - The filler object o.

Return
The newly created builder.

infix fun <T : CharSequence> Expect<T>.contains(expected: CharSequenceOrNumberOrChar): Expect<T> (source)

Expects that the subject of this expectation (a CharSequence) contains the expected's toString representation.

It is a shortcut for contains o atLeast 1 value expected.

Notice that a runtime check applies which assures that only CharSequence, Number and Char are passed. This function expects CharSequenceOrNumberOrChar (which is a typealias for Any) for your convenience, so that you can mix String and Int for instance.

expect("ABC") contains "B"

expect("ABC123") contains values("AB", 'C', 12)

// holds because `contains` does not search for unique matches
// use `contains o exactly 2 value "A"` to check if subject contains two "A"s
expect("ABC") contains values("A", "A")

fails {
    expect("ABC") contains "X"
}

fails { // because subject does not contain all values
    expect("ABC") contains values("A", 99)
}

Exceptions

IllegalArgumentException - in case expected is not a CharSequence, Number or Char.

Return
This assertion container to support a fluent API.

infix fun <T : CharSequence> Expect<T>.contains(values: Values<CharSequenceOrNumberOrChar>): Expect<T> (source)

Expects that the subject of this expectation (a CharSequence) contains the toString representation of the given values using a non disjoint search.

It is a shortcut for contains o atLeast 1 the values(expected, *otherExpected).

Notice that a runtime check applies which assures that only CharSequence, Number and Char are passed. This function expects CharSequenceOrNumberOrChar (which is a typealias for Any) for your convenience, so that you can mix String and Int for instance.

By non disjoint is meant that "aa" in "aaaa" is found three times and not only two times. Also notice, that it does not search for unique matches. Meaning, if the input of the search is "a" and Values is defined as values("a", "a"), then both match, even though they match the same sequence in the input of the search. Use an option such as atLeast, atMost and exactly to control the number of occurrences you expect.

Meaning you might want to use: contains o exactly 2 value "a" instead of: contains values("a", "a")

expect("ABC") contains "B"

expect("ABC123") contains values("AB", 'C', 12)

// holds because `contains` does not search for unique matches
// use `contains o exactly 2 value "A"` to check if subject contains two "A"s
expect("ABC") contains values("A", "A")

fails {
    expect("ABC") contains "X"
}

fails { // because subject does not contain all values
    expect("ABC") contains values("A", 99)
}

Parameters

values - The values which are expected to be contained within the input of the search -- use the function values(t, ...) to create a Values.

Exceptions

IllegalArgumentException - in case one of the values is not a CharSequence, Number or Char.

Return
This assertion container to support a fluent API.

infix fun <T : CharSequence> Expect<T>.contains(pattern: Regex): Expect<T> (source)

Expects that the subject of this expectation (a CharSequence) contains a sequence which matches the given regular expression pattern.

It is a shortcut for contains o atLeast 1 matchFor pattern.

expect("ABC") contains "(B)?C".toRegex()

fails {
    expect("ABC") contains "X".toRegex()
}

Parameters

pattern - The pattern which is expected to have a match against the input of the search.

Return
This assertion container to support a fluent API.

infix fun <T : CharSequence> Expect<T>.contains(regexPatterns: RegexPatterns): Expect<T> (source)

Expects that the subject of this expectation (a CharSequence) contains a sequence which matches the given regular expression regexPatterns, using a non disjoint search.

It is a shortcut for contains o atLeast 1 the regexPatterns(pattern, *otherPatterns).

By non disjoint is meant that "aa" in "aaaa" is found three times and not only two times. Also notice, that it does not search for unique matches. Meaning, if the input of the search is "ab" and RegexPatterns is defined as regexPatterns("a(b)?", "a(b)?") as well, then both match, even though they match the same sequence in the input of the search. Use an option such as atLeast, atMost and exactly to control the number of occurrences you expect.

Meaning you might want to use: contains o exactly 2 regex "a(b)?" instead of: contains o atLeast 1 the regexPatterns("a(b)?", "a(b)?")

// all regex patterns match
expect("ABC") contains regexPatterns("A(B)?", "(B)?C")

// holds because `contains regexPatterns(...)` does not search for unique matches
// use `contains exactly 2 regex "A(B)?"` to check if subject contains the regex two times
expect("ABC") contains regexPatterns("A(B)?", "A(B)?")

fails { // because second regex doesn't match
    expect("ABC") contains regexPatterns("A", "X")
}

Parameters

regexPatterns - The patterns which are expected to have a match against the input of the search -- use the function regexPatterns(t, ...) to create a RegexPatterns.

Return
This assertion container to support a fluent API.

infix fun <T : CharSequence> Expect<T>.contains(patterns: All<Regex>): Expect<T> (source)

Expects that the subject of this expectation (a CharSequence) contains a sequence which matches the given regular expression patterns, using a non disjoint search.

It is a shortcut for contains o atLeast 1 regex All(pattern, *otherPatterns).

By non disjoint is meant that "aa" in "aaaa" is found three times and not only two times. Also notice, that it does not search for unique matches. Meaning, if the input of the search is "ab" and All is defined as all(Regex("a(b)?"), Regex("a(b)?")) as well, then both match, even though they match the same sequence in the input of the search. Use an option such as atLeast, atMost and exactly to control the number of occurrences you expect.

Meaning you might want to use: contains o exactly 2 regex "a(b)?" instead of: contains o atLeast 1 the all(Regex("a(b)?"), Regex("a(b)?"))

// all regex patterns match
expect("ABC") contains all("A".toRegex(), "B".toRegex())

// holds because `contains all(...)` does not search for unique matches
// use `contains exactly 2 regex regex` to check if subject contains the regex two times
val regex = "A(B)?".toRegex()
expect("ABC") contains all(regex, regex)

fails { // because second regex doesn't match
    expect("ABC") contains all("A".toRegex(), "X".toRegex())
}

Parameters

patterns - The patterns which are expected to have a match against the input of the search -- use the function all(Regex(...), ...) to create a All.

Return
This assertion container to support a fluent API.

infix fun <E, T : Iterable<E>> Expect<T>.contains(expected: E): Expect<T> (source)

Expects that the subject of this expectation (an Iterable) contains the expected value.

It is a shortcut for contains o inAny order atLeast 1 value expected

infix fun <E, T : Iterable<E>> Expect<T>.contains(values: Values<E>): Expect<T> (source)

Expects that the subject of this expectation (an Iterable) contains the expected values.

It is a shortcut for contains o inAny order atLeast 1 the values(...)

Notice, that it does not search for unique matches. Meaning, if the iterable is setOf('a', 'b') and Values is defined as values("a", "a"), then both match, even though they match the same sequence in the input of the search. Use an option such as atLeast, atMost and exactly to control the number of occurrences you expect.

It is a shortcut for contains o inAny order atLeast 1 entry assertionCreatorOrNull

Parameters

assertionCreatorOrNull - The identification lambda which creates the assertions which the entry we are looking for has to hold; or in other words, the function which defines whether an entry is the one we are looking for or not.

Delegates to it contains o inAny order keyValuePairs keyValuePairs

Notice, that it does not search for unique matches. Meaning, if the map is mapOf('a' to 1) and one of the Pair in keyValuePairs is defined as 'a' to 1 and another one is defined as 'a' to 1 as well, then both match, even though they match the same entry.

Parameters

keyValuePairs - The key-value Pairs expected to be contained within this Map -- use the function pairs(x to y, ...) to create a Pairs.

Return
an Expect for the subject of this expectation.

Expects that the subject of this expectation (a Map) contains a key as defined by keyValue's KeyWithValueCreator.key with a corresponding value which either holds all assertions keyValue's KeyWithValueCreator.valueAssertionCreatorOrNull creates or needs to be null in case KeyWithValueCreator.valueAssertionCreatorOrNull is defined as null

Delegates to it contains o inAny order keyValue keyValue

Parameters

keyValue - The KeyWithValueCreator whose key is expected to be contained within this Map and where the corresponding value holds all assertions the KeyWithValueCreator.valueAssertionCreatorOrNull creates or needs to be null in case KeyWithValueCreator.valueAssertionCreatorOrNull is defined as null -- use the function keyValue(x) { ... } to create a KeyWithValueCreator.
