Constructor Details

FluentResponseBodyAssertion

public FluentResponseBodyAssertion(ResponseContent value,
 R returns)

Constructor.

Parameters:

value - The object being tested.
Can be null.

returns - The object to return after a test method is called.
If null, the test method returns this object allowing multiple test method calls to be used on the same assertion.

FluentResponseBodyAssertion

public FluentResponseBodyAssertion(Assertion creator,
 ResponseContent value,
 R returns)

Chained constructor.

Used when transforming one assertion into another so that the assertion config can be used by the new assertion.

Parameters:

creator - The assertion that created this assertion.
Should be null if this is the top-level assertion.

value - The object being tested.
Can be null.

returns - The object to return after a test method is called.
If null, the test method returns this object allowing multiple test method calls to be used on the same assertion.

Method Details

asString

public FluentStringAssertion<R> asString()

Provides the ability to perform fluent-style assertions on this response body.

Examples:

// Validates the response body equals the text "OK". client .get(URI) .run() .assertContent().is("OK"); // Validates the response body contains the text "OK". client .get(URI) .run() .assertContent().isContains("OK"); // Validates the response body passes a predicate test. client .get(URI) .run() .assertContent().is(x -> x.contains("OK")); // Validates the response body matches a regular expression. client .get(URI) .run() .assertContent().isPattern(".*OK.*"); // Validates the response body matches a regular expression using regex flags. client .get(URI) .run() .assertContent().isPattern(".*OK.*", MULTILINE & CASE_INSENSITIVE); // Validates the response body matches a regular expression in the form of an existing Pattern. Pattern pattern = Pattern.compile(".*OK.*"); client .get(URI) .run() .assertContent().isPattern(pattern);

The assertion test returns the original response object allowing you to chain multiple requests like so:

// Validates the response body matches a regular expression. MyBean bean = client .get(URI) .run() .assertContent().isPattern(".*OK.*"); .assertContent().isNotPattern(".*ERROR.*") .getContent().as(MyBean.class);

Notes:

• If no charset was found on the Content-Type response header, "UTF-8" is assumed.
• When using this method, the body is automatically cached by calling the ResponseContent.cache().
• The input stream is automatically closed after this call.

Overrides:

asString in class FluentObjectAssertion<ResponseContent,R>

Returns:

A new fluent assertion object.

asBytes

public FluentByteArrayAssertion<R> asBytes()

Provides the ability to perform fluent-style assertions on the bytes of the response body.

Examples:

// Validates the response body equals the text "foo". client .get(URI) .run() .assertContent().asBytes().asHex().is("666F6F");

Notes:

• If no charset was found on the Content-Type response header, "UTF-8" is assumed.
• When using this method, the body is automatically cached by calling the ResponseContent.cache().
• The input stream is automatically closed after this call.

Returns:

A new fluent assertion object.

as

public <T> FluentAnyAssertion<T,R> as(Class<T> type)

Converts the body to a type using ResponseContent.as(Class) and then returns the value as an object assertion.

Examples:

// Validates the response body as a list of strings and validates the length. client .get("/myBean") .run() .assertContent().as(List.class, String.class).is(x -> x.size() > 0);

Type Parameters:

T - The object type to create.

Parameters:

type - The object type to create.

Returns:

A new fluent assertion object.

as

public FluentAnyAssertion<Object,R> as(Type type,
 Type... args)

Converts the body to a type using ResponseContent.as(Type,Type...) and then returns the value as an object assertion.

Examples:

// Validates the response body as a list of strings and validates the length. client .get("/myBean") .run() .assertContent().as(List.class, String.class).is(x -> x.size() > 0);

See Complex Data Types for information on defining complex generic types of Maps and Collections.

Parameters:

type - The object type to create.

args - Optional type arguments.

Returns:

A new fluent assertion object.

valueAsString

protected String valueAsString()
                        throws AssertionError

Description copied from class: FluentObjectAssertion

Returns the inner value as a string.

Overrides:

valueAsString in class FluentObjectAssertion<ResponseContent,R>

Returns:

The inner value as a string, or null if the value was null.

Throws:

AssertionError

setMsg

public FluentResponseBodyAssertion<R> setMsg(String msg,
 Object... args)

Description copied from class: Assertion

Allows you to override the assertion failure message.

String can contain "{msg}" to represent the original message.

Example:

import static org.apache.juneau.assertions.Assertions.*; // Throws an assertion with a custom message instead of the default "Value was null." assertString(myString) .setMsg("My string was bad: {msg}") .isNotNull();

Overrides:

setMsg in class FluentObjectAssertion<ResponseContent,R>

Parameters:

msg - The assertion failure message.

args - Optional message arguments.

Returns:

This object.

setOut

public FluentResponseBodyAssertion<R> setOut(PrintStream value)

Description copied from class: Assertion

If an error occurs, send the error message to the specified stream instead of STDERR.

Overrides:

setOut in class FluentObjectAssertion<ResponseContent,R>

Parameters:

value - The output stream. Can be null to suppress output.

Returns:

This object.

setSilent

public FluentResponseBodyAssertion<R> setSilent()

Description copied from class: Assertion

Suppresses output to STDERR.

This is the equivalent to calling out(null).

Overrides:

setSilent in class FluentObjectAssertion<ResponseContent,R>

Returns:

This object.

setStdOut

public FluentResponseBodyAssertion<R> setStdOut()

Description copied from class: Assertion

If an error occurs, send the error message to STDOUT instead of STDERR.

Overrides:

setStdOut in class FluentObjectAssertion<ResponseContent,R>

Returns:

This object.

setThrowable

public FluentResponseBodyAssertion<R> setThrowable(Class<? extends RuntimeException> value)

Description copied from class: Assertion

If an error occurs, throw this exception instead of the standard AssertionError.

The throwable class must have a public constructor that takes in any of the following parameters:

• Throwable - The caused-by exception (if there is one).
• String - The assertion failure message.

If the throwable cannot be instantiated, a RuntimeException is thrown instead.

Example:

import static org.apache.juneau.assertions.Assertions.*; // Throws a BadRequest instead of an AssertionError if the string is null. assertString(myString) .setThrowable(BadRequest.class) .isNotNull();

Overrides:

setThrowable in class FluentObjectAssertion<ResponseContent,R>

Parameters:

value - The new value for this setting.

Returns:

This object.
