So in my global.asax, I've got the following code:
Inventory.BusinessTier bt = new Inventory.BusinessTier();
string UserLogin = bt.ExtractLogin (Request.ServerVariables ["AUTH_USER"]);
Inventory.User myUser = new Inventory.User (UserLogin);
Session ["User"] = myUser;
It works just fine on one development PC, but using the same version of Visual Studio, it craps out on the third line with this error:
System.TypeInitializationException: 'The type initializer for
'Inventory.DataTier' threw an exception.'
Inner Exception
NullReferenceException: Object reference not set to an instance of an
object.
Other than a line adding impersonation in my web.config (it has to be there now), I haven't changed a single thing. Is there a way to get more info on this? I can't even trace it, because if I put a debug line in the User object constructor, it never hits it. I'm at a bit of a loss. Would appreciate any advice.
EDIT to answer questions below:
InventoryUser is a very simple user object that reads the current from the database and stores some basic user info in properties, such as UserID, Role, RoleID, and IsAdmin.
The DataTier class is a class that interacts with the database. It is used in multiple projects, so I'm quite sure it's not the problem. I tried to paste in the code anyway, but it exceeded the limit for a post.
I'm reasonably sure the problem is related to the user class. It's short, so I can paste it in here:
using System;
using System.Data;
// This is the user business object. It contains information pertaining to the current user of the application. Notably, it
// contains the department ID, which determines what inventory items the user will see when using the application. Only
// specified employees with admin access can see all items for all departments, and that is determined by a specific department ID.
namespace Inventory {
public class User {
private Guid _UserID;
private Guid _RoleID;
private Guid _UserDepartmentID;
private string _UserRole = "";
private string _UserName = "";
private bool _IsAuthorizedUser = false;
private bool _IsAdmin = false;
// Attribute declarations
public Guid UserID {
get {
return _UserID;
}
set {
_UserID = value;
}
}
public string UserRole {
get {
return _UserRole;
}
set {
_UserRole = value;
}
}
public Guid RoleID {
get {
return _RoleID;
}
set {
_RoleID = value;
}
}
public string UserName {
get {
return _UserName;
}
set {
_UserName = value;
}
}
public Guid UserDepartmentID {
get {
return _UserDepartmentID;
}
set {
_UserDepartmentID = value;
}
}
public bool IsAdmin {
get {
return _IsAdmin;
}
set {
_IsAdmin = value;
}
}
public bool IsAuthorizedUser {
get {
return _IsAuthorizedUser;
}
set {
_IsAuthorizedUser = value;
}
}
// -----------------
// - Constructor -
// -----------------
public User (string UserLogin) {
string ShortUserLogin = ExtractLogin (UserLogin);
GetUser (ShortUserLogin);
}
// ------------------
// - ExtractLogin -
// ------------------
public string ExtractLogin (string Login) {
// The domain and "\" symbol must be removed from the string, leaving only the user name.
int pos = Login.IndexOf (#"\");
return Login.Substring (pos + 1, Login.Length - pos - 1);
}
// -------------
// - GetUser -
// -------------
// This method is called to fill the user object based on the user's login. It ultimately gets authorized user data
// from the user table.
public void GetUser (string UserName) {
DataTier dt1 = new DataTier();
DataTable dt = dt1.GetUserInfo (UserName);
int RecordCount = dt.Rows.Count;
switch (RecordCount) {
case 1: // There is one user name match, as there should be. This is the likely situation.
DataRow dr = dt.Rows[0];
UserID = (Guid)dr ["UserID"];
UserRole = (string)dr ["UserRole"];
RoleID = (Guid)dr ["RoleID"];
this.UserName = UserName;
UserDepartmentID = (Guid)dr ["DepartmentID"];
IsAdmin = (bool)dr ["IsAdmin"];
IsAuthorizedUser = true;
break;
case 0: // There are no user name matches (unauthorized use).
IsAdmin = false;
IsAuthorizedUser = false;
break;
default: // There are multiple user name matches (problem!).
IsAdmin = false;
IsAuthorizedUser = false;
break;
}
}
}
}
I have a TestNG test that has multiple methods. The extent report works in the main class but when I try to write logs for the other methods I am getting null pointer exception. All the tutorials point to writing logs in the main method but not to the other methods. I have been struggling to find a solution for this for a week now. Can somebody help me please ? Thanks
My code is some thing like this
#Test
public void TestOne()
{
extentTest = extent.startTest("TestOne");
Login.LoginToClient();
Access.AccessMainPage();
-
-
}
Public void LoginToClient()
{
***How can write an extent report log here for example - "Enter Username"
driver.findElement(By.id("username")).SendKeys(username)
-
-
}
The following is written in the main test
#BeforeTest
public void setExtent(){
extent = new ExtentReports(System.getProperty("user.dir")+"/test-output/ExtentReport.html", true);
extent.addSystemInfo("Host Name", "Calcutta");
extent.addSystemInfo("User Name", "Admin");
extent.addSystemInfo("Environment", "QA");
}
#AfterMethod
public void tearDown(ITestResult result) throws IOException {
if(result.getStatus()==ITestResult.FAILURE){
//to add name in extent report
extentTest.log(LogStatus.FAIL, "TEST CASE FAILED IS "+result.getName());
//to add error/exception in extent report
extentTest.log(LogStatus.FAIL, "TEST CASE FAILED IS "+result.getThrowable());
String screenshotPath = Screenshots.getScreenshot(driver, result.getName());
//to add screenshot in extent report
extentTest.log(LogStatus.FAIL, extentTest.addScreenCapture(screenshotPath));
}
else if(result.getStatus()==ITestResult.SKIP){
extentTest.log(LogStatus.SKIP, "Test Case SKIPPED IS " + result.getName());
}
else if(result.getStatus()==ITestResult.SUCCESS){
extentTest.log(LogStatus.PASS, "Test Case PASSED IS " + result.getName());
}
extent.endTest(extentTest);
}

Please check these links for the answer:
How to print logs by using ExtentReports listener in java?
https://github.com/cbeust/testng/blob/master/src/main/java/org/testng/reporters/EmailableReporter2.java
If you have a Reporting Class say which Listens to the TestNG Listner and have ExtentReport code implemented in it you can get the TestCase Steps using Reporter Object
please see below.
Note that Reporter .log of TestNG does not have any definition for Type of Log like INFO, FATAL etc.. It just adds the Log Message.
Test case:
public class TC_1 extends BaseClass{
#Test (priority=0)
public void addNotes() throws Exception
{
if (super.search("VALUE"))
{
logger.info("Search is Successful");
Reporter.log("Search is Successful");
Assert.assertTrue(true);
}
}
Reporting:
public class Reporting extends TestListenerAdapter
{
public ExtentHtmlReporter htmlReporter;
public ExtentReports extent;
public ExtentTest logger;
public void onStart(ITestContext testContext)
{
String timeStamp = new SimpleDateFormat("yyyy.MM.dd.HH.mm.ss").format(new Date());//time stamp
String repName="Test-Report-"+timeStamp+".html";
htmlReporter=new ExtentHtmlReporter(System.getProperty("user.dir")+ "/test-output/"+repName);//specify location of the report
htmlReporter.loadXMLConfig(System.getProperty("user.dir")+ "/extent-config.xml");
extent=new ExtentReports();
extent.attachReporter(htmlReporter);
htmlReporter.config().setDocumentTitle("Test Project");
htmlReporter.config().setReportName("Functional Test Automation Report");
htmlReporter.config().setTestViewChartLocation(ChartLocation.TOP);
htmlReporter.config().setTheme(Theme.DARK);
}
public void onTestSuccess(ITestResult tr)
{
logger=extent.createTest(tr.getName());
logger.log(Status.PASS,MarkupHelper.createLabel(tr.getName(),ExtentColor.GREEN));
List<String> reporterMessages = Reporter.getOutput(tr);
for (int i = 0; i < reporterMessages.size(); i++)
{
System.out.println(reporterMessages.get(i));
logger.info(reporterMessages.get(i));
}
}
}
Firstly, I recommend to use Version 3 instead of Version 2,
As I can see in your Code, You have define Test definition but there is no such logs for that method in which you wants to generate,
Please Refer as Following, to generate logs:
You can use same way in any method,
extentTest.log(LogStatus.INFO, "Test Case Details");
Here object of ExtentTest need to declare as Class variable, So you can access it anywhere within class.
If you wants to create different Test section for Login.LoginToClient(); method, you can define it like:
Public void LoginToClient()
{
extentTest = extent.startTest("Login Test");
driver.findElement(By.id("username")).SendKeys(username);
extentTest.log(LogStatus.INFO, "User Name: " +username);
}
Hope it will works as you want to generate.
I am following https://github.com/pardom/ActiveAndroid/wiki/Querying-the-database to incorporate activeandroid in my application like so:
#Table(name="Contact")
public class Contact extends Model implements Serializable, Comparable {
public Contact() {
super();
}
public Contact(String id, String n, String c, String p, String addr, String phone,
String fb, String twit, String yt) {
super();
candID = id;
name = n;
chamber = c;
party = p;
address = addr;
phoneNo = phone;
facebook = fb;
twitter = twit;
youtube = yt;
}
public static List<Contact> getCachedContactsByState(String stateAbbr) {
/*return new Select().from(Contact.class).where("state = ?",
stateAbbr).execute();*/
Select s = new Select();
From f = s.from(Contact.class);
f = f.where("state = ?", stateAbbr);
List<Contact> cachedContacts = f.execute();
return cachedContacts;
}
According to my debugger, the f.execute throws a null pointer exception, and f is not null.
just making sure, the tutorial didn't mention needing to install sqlite before using activeandroid, and it said the point of activeandroid was to use objects and their functions to do CRUD on sqlite, so I'm assuming I just needed to follow the tutorial to create and query my sqlite db?
Looks like you've forgotten to call ActiveAndroid.initialize() with a valid Context. See the Getting Started section from the documentation you linked to.
I have this code below. Gets data and sets data property to the values gathered.
public struct TrblShootData
{
public List<string> Logins;
public IEnumerable<Hieracrhy> Hierarchy;
public IEnumerable<EmployeeTeam> EmpTeam;
}
public TrblShootData TroubleShootData
{
get;
private set;
}
class DataGetter
{
public void GetData(string FirstName, string LastName, string Login, string Email, bool isFirstName, bool isLastName, bool isLogin, bool isEmail)
{
List<string> logins = null;
IEnumerable<Hieracrhy> hier = null;
IEnumerable<EmployeeTeam> tmemp = null;
TrblShootData tsData = new TrblShootData();
queries q = BuildQuery(FirstName, LastName, Login, Email, isFirstName, isLastName, isLogin, isEmail);
if (q.isValidQueries)
{
DataContext1 mscDB = new DataContext1 ();
using (DataContext2 opsDB = new DataContext2 ())
{
tmemp = opsDB.ExecuteQuery<EmployeeTeam>(q.qryEmployeeTeam);
}
using (DataContext3 rptDB = new DataContext3 ())
{
hier = rptDB.ExecuteQuery<Hieracrhy>(q.qryHierarchy);
if (hier != null)
{
logins = hier.Select(s => s.SalesRepLogin).Distinct().ToList();
}
}
tsData.EmpTeam = tmemp.Select(r=>r);
tsData.Hierarchy = hier.Select(r => r);
tsData.Logins = logins.Select(r => r).ToList();
TroubleShootData = tsData;
}//if
}
}
From another class I attempt to do this:
tshtr.GetData(txtFirstName.Text, txtLastName.Text, txtLogin.Text, txtEmail.Text, chkFirstName.Checked, chkLastName.Checked, chkLogin.Checked, chkEmail.Checked);
gvEmpTeams.DataSource = tshtr.TroubleShootData.EmpTeam;
gvHierarchy.DataSource = tshtr.TroubleShootData.Hierarchy;
gvEmpTeams.DataBind();
gvHierarchy.DataBind();
But at the DataBind() I get an error saying that I cannot read from a closed reader.
I'm not seeing why it would throw this error when I've set my property as above after I've assigned the values in the usings. So I'm not seeing how this is trying to use a closed reader.
Thanks for any help!
Because of deferred execution, your query only executes when the data-binding engine enumerates its results, after you close the DataContext.
You need to call .ToList() before closing the DataContext to force it to be evaluated immediately.
