Method Detail

hasContentEqualTo

@Deprecated
public SELF hasContentEqualTo(InputStream expected)

Deprecated.

use hasSameContentAs(InputStream) instead

Verifies that the content of the actual InputStream is equal to the content of the given one.

Parameters:

expected - the given InputStream to compare the actual InputStream to.

Returns:

this assertion object.

Throws:

NullPointerException - if the given InputStream is null.

AssertionError - if the actual InputStream is null.

AssertionError - if the content of the actual InputStream is not equal to the content of the given one.

InputStreamsException - if an I/O error occurs.

hasSameContentAs

public SELF hasSameContentAs(InputStream expected)

Verifies that the content of the actual InputStream is equal to the content of the given one.

Example:

 // assertion will pass
 assertThat(new ByteArrayInputStream(new byte[] {0xa})).hasSameContentAs(new ByteArrayInputStream(new byte[] {0xa}));

 // assertions will fail
 assertThat(new ByteArrayInputStream(new byte[] {0xa})).hasSameContentAs(new ByteArrayInputStream(new byte[] {}));

Parameters:

expected - the given InputStream to compare the actual InputStream to.

Returns:

this assertion object.

Throws:

NullPointerException - if the given InputStream is null.

AssertionError - if the actual InputStream is null.

AssertionError - if the content of the actual InputStream is not equal to the content of the given one.

InputStreamsException - if an I/O error occurs.

hasContent

public SELF hasContent(String expected)

Verifies that the content of the actual InputStream is equal to the given String.

Example:

 // assertion will pass
 assertThat(new ByteArrayInputStream("a".getBytes())).hasContent("a");

 // assertions will fail
 assertThat(new ByteArrayInputStream("a".getBytes())).hasContent("");
 assertThat(new ByteArrayInputStream("a".getBytes())).hasContent("ab");

Parameters:

expected - the given String to compare the actual InputStream to.

Returns:

this assertion object.

Throws:

NullPointerException - if the given String is null.
