### Question:
ParameterContainer { public boolean removeParameterShell(final ParameterShell parameterShell) { return parameterShells.remove(parameterShell); }  boolean removeParameterShell(final ParameterShell parameterShell); boolean removeParameterShell(final String parameterName); void addParameterShell(final ParameterShell parameterShell); void addParameterShell(final String parameterName, final String... parameterValue); void addParameterShell(final String parameterName, final ITime... parameterValue); void addParameterShell(final String parameterName, final Integer... parameterValue); void addParameterShell(final String parameterName, final ParameterContainer... parameterValue); ParameterShell getParameterShellWithCommonName(final String commonName); ParameterShell getParameterShellWithServiceSidedName(final String serviceSidedName); boolean containsParameterShellWithServiceSidedName(final String serviceSidedName); boolean containsParameterShellWithCommonName(final String commonName); void setParameterValue(final String commonName, final Object newValue); void setParameterValueArray(final String commonName, final Object[] newValues); List<ParameterShell> getParameterShells(); @Override String toString();  }### Answer:
@Test public void removeParameterShell_by_parameterName_should_return_false_if_shell_is_NOT_contained() throws OXFException { final ParameterContainer container = new ParameterContainer(); final boolean isShellRemoved = container.removeParameterShell("any-name"); assertThat(isShellRemoved, is(FALSE)); }
