    <p>This question is next to the question I had asked <a href="https://stackoverflow.com/questions/9138555/spring-framework-test-restful-web-service-controller-offline-i-e-no-server-n">here</a>. I am using <strong>spring-test-mvc</strong> framework to test <strong>REST</strong> controller. Please see the above link to see my code for the REST Controller I have.</p> <p>My test for <strong>GET</strong> is working fine but I can't do a <strong>POST</strong>. I get an exception when I try do so. This is my first time testing a REST controller.</p> <p>Here's my PcUserControllerTest class</p> <pre><code>@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = "classpath:/applicationContextTest.xml") public class PcUserControllerTest { @Autowired PcUserService pcUserService; @Autowired PcUserController pcUserController; PcUser pcUser; private MockMvc mockMvc; @Before public void setUp() throws Exception { mockMvc = standaloneSetup(pcUserController).build(); pcUser = new PcUser("John", "Li", "Weasley", "john", "john"); pcUserService.create(pcUser); } @After public void tearDown() throws Exception { pcUserService.delete(pcUser.getId()); } @Test public void shouldGetPcUser() throws Exception { this.mockMvc.perform(get("/pcusers/" + pcUser.getId()).accept(MediaType.APPLICATION_JSON)).andExpect(status().isOk()); } @Test public void shouldCreatePcUser() throws Exception { PcUser newUser = new PcUser("Mike", "Li", "Donald", "mike", "mike"); this.mockMvc.perform(post("/pcusers/create/" + newUser).accept(MediaType.APPLICATION_JSON)).andExpect(status().isOk()); } } </code></pre> <p>Exception I get when I execute shouldCreatePcUser:</p> <pre><code>java.lang.IllegalArgumentException: Not enough variable values available to expand ["firstName"] at org.springframework.web.util.UriComponents$VarArgsTemplateVariables.getValue(UriComponents.java:1011) at org.springframework.web.util.UriComponents.expandUriComponent(UriComponents.java:443) at org.springframework.web.util.UriComponents.access$1(UriComponents.java:431) at org.springframework.web.util.UriComponents$FullPathComponent.expand(UriComponents.java:790) at org.springframework.web.util.UriComponents.expandInternal(UriComponents.java:413) at org.springframework.web.util.UriComponents.expand(UriComponents.java:404) at org.springframework.web.util.UriTemplate.expand(UriTemplate.java:121) at org.springframework.test.web.server.request.MockMvcRequestBuilders.expandUrl(MockMvcRequestBuilders.java:51) at org.springframework.test.web.server.request.MockMvcRequestBuilders.request(MockMvcRequestBuilders.java:45) at org.springframework.test.web.server.request.MockMvcRequestBuilders.post(MockMvcRequestBuilders.java:28) at com.project.cleaner.controller.test.PcUserControllerTest.shouldCreatePcUser(PcUserControllerTest.java:69) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.springframework.test.context.junit4.statements.RunBeforeTestMethodCallbacks.evaluate(RunBeforeTestMethodCallbacks.java:74) at org.springframework.test.context.junit4.statements.RunAfterTestMethodCallbacks.evaluate(RunAfterTestMethodCallbacks.java:83) at org.springframework.test.context.junit4.statements.SpringRepeat.evaluate(SpringRepeat.java:72) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:231) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184) at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61) at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:71) at org.junit.runners.ParentRunner.run(ParentRunner.java:236) at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:174) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) </code></pre> <p>My PcUser looks like </p> <pre><code>@Document public class PcUser extends BaseEntity { private String firstName;

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
