I am learning to use the JMockit to test my Restful API.The missing invocation error is abusing me.
The Restful API:
#RestController
public class AgentInfoRest {
#Autowired
AgentInfoRepository agentInfoRepository;
private Logger logger = LoggerFactory.getLogger(AgentInfoRest.class);
#RequestMapping("/allagentInfo")
RestResponse getAllAgentInfo()
{
RestResponse restResponse = new RestResponse();
logger.info("getAllAgentInfo has no request parameter");
Collection<AgentInfo> result = agentInfoRepository.getAllAgents();
if(result.isEmpty())
{
restResponse.setRetCode(-1);
restResponse.setRetMsg("Request success,no such record in db");
}
restResponse.setResult(result);
return restResponse;
}
}
The Test Class:
public class AgentInfoRestTest {
String host = "http://127.0.0.1:8080";
#Test
public void getAllAgentInfoTest(#Mocked final AgentInfoRepository agentInfoRepository) {
RestTemplate restTemplate = new RestTemplate();
RestResponse restResponse = new RestResponse();
AgentInfoRest agentInfoRest = new AgentInfoRest();
new StrictExpectations() {
{
agentInfoRepository.getAllAgents(); result = null; times = 1;
}
};
String url = "/allagentInfo";
ResponseEntity<RestResponse> result = restTemplate.getForEntity(host + url, RestResponse.class);
new FullVerifications() {
{
}
};
}
}
The Error:
mockit.internal.MissingInvocation: Missing invocation of:

Good day Pals,
I am new to Springboot and having problems testing my PDF uploader spring controller endpoint.
The rest endpoint works when tested via postman, but not in my unit test.
I am using a spring boot application with the following key components and problem is:
org.springframework.web.bind.MissingServletRequestParameterException: Required MultipartFile parameter 'file' is not present
at org.springframework.web.method.annotation.RequestParamMethodArgumentResolver.handleMissingValue(RequestParamMethodArgumentResolver.java:251)

Please, see some code and stacktrace below ... I have been banging my head on the wall all day, debugging using all online references but NO luck ....

The Cloudant version is 2.4.2
<dependency>
<groupId>com.cloudant</groupId>
<artifactId>cloudant-client</artifactId>
<version>2.4.2</version>
</dependency>
If anyone used to found this problem, please let me know the better solution than I have to restart my application every day.
The problem you describe sounds identical to one that was resolved in version 2.4.1.
I would check to make sure you don't have multiple versions of the cloudant-client included in your application or classpath and that your application is really using version 2.4.2. The line numbers in the stack trace you provide do not match with the source for 2.4.2.
I want to configure Tomcat 8 with PostgreSQL
I added this in context.xml
<Resource name="jdbc/DefaultDB" auth="Container" type="javax.sql.DataSource"
username="postgres" password="qwerty"
url="jdbc:postgresql://localhost:5432/crm"
driverClassName="org.postgresql.Driver"
initialSize="5" maxWait="5000"
maxActive="120" maxIdle="5"
validationQuery="select 1"
poolPreparedStatements="true"/>
And I tried to run this Java code:
public String init()
{
String user_name = null;
try
{
Context ctx = new InitialContext();
if (ctx == null)
throw new Exception("Boom - No Context");
DataSource ds = (DataSource) ctx.lookup("jdbc/DefaultDB");
if (ds != null)
{
Connection conn = ds.getConnection();
if (conn != null)
{
Statement stmt = conn.createStatement();
ResultSet rst = stmt.executeQuery("select id, user_name from user where username = " + user);
if (rst.next())
{
user_name = rst.getString("user_name");
}
conn.close();
}
}
}
catch (Exception e)
{
e.printStackTrace();
}
return user_name;
}
But for some reason after I added this code Tomcat is not starting. Do you have any idea where I'm wrong?
I get this in Tomcat log file:
28-Mar-2016 10:37:07.955 WARNING [localhost-startStop-1] org.apache.tomcat.dbcp.dbcp2.BasicDataSourceFactory.getObjectInstance Name = DefaultDB Property maxActive is not used in DBCP2, use maxTotal instead. maxTotal default value is 8. You have set value of "120" for "maxActive" property, which is being ignored.

javax.naming.NameNotFoundException: Name [jdbc/DefaultDB] is not bound in this Context. Unable to find [jdbc].
as #a_horse_with_no_name says, your lookup is wrong. your code must be like this:
public String init()
{
String user_name = null;
try
{
Context ctx = new InitialContext();
if (ctx == null)
throw new Exception("Boom - No Context");
Context envCtx = (Context) ctx.lookup("java:comp/env");
DataSource ds = (DataSource) envCtx.lookup("jdbc/DefaultDB");
if (ds != null)
{
Connection conn = ds.getConnection();
if (conn != null)
{
Statement stmt = conn.createStatement();
ResultSet rst = stmt.executeQuery("select id, user_name from user where username = " + user);
if (rst.next())
{
user_name = rst.getString("user_name");
}
conn.close();
}
}
}
catch (Exception e)
{
e.printStackTrace();
}
return user_name;
}
I am writing crm2011 plugin in "Email" entity with "Send" Message of Pre_operation. What i want to do is when i click "Send" button in email entity, I do the necessary checking before send. If the checking is not correct, I want to prevent and stop the sending email and show "the alert message" and stop the second plugin(this plugin send email and create the associated entity to convert "Case"). Please give me some suggestion for that plugin?
Should i use pre-Validation stage or Pre_operation state? And how can I return false to stop plugin.

_serviceProvider = serviceProvider;

Well stopping the plugin is dead easy you just throw InvalidPluginException, the message you give it will be shown to the user in a alert window. You will have to do this on the pre of the send. In this case I don't think it will matter if its pre-validation or pre-operation.
Edit:
Yes, you should throw an InvalidPluginException even if no exception has happened in code. I accept this isnt what we would normally do, but its the way its meant to work. Msdn has more details: http://msdn.microsoft.com/en-us/library/gg334685.aspx
So for example the code would look like:
public void Execute(IServiceProvider serviceProvider)
{
try
{
//This is where we validate the email send
if(emailIsOkay)
{
//Do something
}
else if(emailIsNotOkay)
{
//Throw and exception that will stop the plugin and the message will be shown to the user (if its synchronous)
throw new InvalidPluginExecutionException("Hello user, your email is not correct!!");
}
}
catch (InvalidPluginExecutionException invalid)
{
//We dont to catch exception for InvalidPluginExecution, so just throw them on
throw;
}
catch (Exception ex)
{
//This exception catches if something goes wrong in the code, or some other process.
throw new InvalidPluginExecutionException(ex.Message, ex);
}
