assertThat( str, startsWith( "bjsxt" ) );
assertThat( n, equalTo( nExpected ) );
assertThat( str, equalToIgnoringCase( "bjsxt" ) );
assertThat( str, equalToIgnoringWhiteSpace( "bjsxt" ) );
c) assertThat( d, closeTo( 3.0, 0.3 ) );
assertThat( d, greaterThan(3.0) );
assertThat( d, lessThan (10.0) );
assertThat( d, greaterThanOrEqualTo (5.0) );
assertThat( d, lessThanOrEqualTo (16.0) );
d) assertThat( map, hasEntry( "bjsxt", "bjsxt" ) );
