python - AssertionError: Exception not raised -


i have unittest test custom exception raised properly. got assertionerror: invalidlength not raised

below unit test

@patch('services.class_entity.validate') @patch('services.class_entity.jsonify') def test_should_raise_invalid_length_exception(self, mock_jsonify, mock_validate):     mock_validate.return_value = true      data = self.data     data['traditional_desc'] = "contrary popular"     mock_jsonify.return_value = {         "success": false,         "results": {             "message": "invalid value traditional_desc"         }     }      self.assertraises(invalidlength) cm:         benefittemplateservice.create(data)

and function i'm testing

class benefittemplateservice(object):      @staticmethod     def create(params):          try:             required_fields = ['company_id', 'name', 'behavior', 'benefit_type']             valid = is_subset(params, required_fields)              if not valid:                 raise missingparameter              if not validate_string(params['traditional_desc'], 0, 1000, characters_supported="ascii"):                 raise invalidlength(400, "invalid value traditional_desc")              # call create here             response = benefittemplateentitymanager.create_template(params)             return response          except invalidlength e:             response = {                 "success": false,                 "results": {                     "message": e.message                 }             }              return jsonify(response), e.code

the except invalidlength working because if try print execute line of code. assumed invalidlength exception being called i'm not sure on result of unittest fails. can please

create raises invalidlength exception catches , handles silently, test expects raise it.

use different assert assertraises. except block returns json, test can check json's content.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
