i've been working apollojs in react (via react-apollo ) past several months , have learned number of tricks , challenges associated unit testing apollo-wrapped components. when testing component directly wrapped apollo, export , test component before wrapped hoc returned graphql . when testing component has apollo-wrapped component descendant, use enzyme's shallow rendering whenever possible prevent descendant mounting. if full-dom rendering via mount required, use mockedprovider apollo's test utils descendants don't throw error trying access this.context . i have not found solution, however, following case: component apollo-wrapped descendants needs tested using full-dom rendering need make assertions involving component instance (e.g. state, instance methods, etc). avoid issues descendants, have wrap component in mocked provider, means assertions on wrapper operating on mockedprovider instance , not component want testing. an example: import { mount }

i'm using eclipse (neon.3 release (4.6.3)) pydev plugin python. the code i'm debugging has large number of variables, many of nested within other variables. i'd select subset of these variables included in separate view can bypass having drill down variables @ each step, tedious process. the primary data structure being used pandas dataframe containing numerous columns, , typically need see small portion of values few of dataframe's columns. for example, let's have dataframe 'df' column named 'x'. whenever debug code want see values of df.x between indices , j (i.e. df.x[i:j+1]). , j may change time time they're variables in code not in 'df'. how can create streamlined tab/view of variables includes df.x._values[i:j+1], preferably separate standard variables view? thanks in advance suggestions or feedback in general. this can done using 'expressions' view within debug perspective. for example in question abo

after login form autocompleted browser, queried password input's value empty. after click password field, value gets magically available, there many events fired browser don't make sense. (the onchange on password input not among them.) why value on input[type=password] empty? why autocomplete on password input doesn't fire onchange event? ( fires on normal input ) bonus question: why there second (unnecessary) focus/blur event? 1. both inputs set type="text" both inputs rendered once (no autocomplete) note: inputs uncontrolled stateful , track state changes on focus, blur, change entered=true when there value entered focused=true when onfocus fired, =false when onblur fired peek=true when need programatically force type password to  text 2. input set type="password" (see how form autocompleted.) ... 2.render ( red arrow ) - browser focused input onchange fired on email input 3.render - i

i'm implementing wpf datagrid contains projects many key figures. projects grouped project categories. for each category there should be: a row shows in each key figure column sum of rows column. a target row not part of datasource grid in binded to. target row tells every column target year (e.g. how money there's spend). these rows should on top in each group (sorting filtering). my 1st solution have data in group header. not solution because group header not support columns. i.e. should constructed getting column widths. that done gets complicated when users want reorder , hide columns. datagrid using collectionviewsource it's not populated c# code. i'm extending example: http://msdn.microsoft.com/en-us/library/ff407126.aspx thanks & best regards - matti i have hacked-together datagrid group subtotal rows in 1 of projects. weren't concerned of issues bring up, such hiding , sorting columns don't know sure if can extended that

i'm writing , manipulating massive text files (180+mb). , i'm trying come memory schema handle data. bigfile.txt \r delimited list of strings. my current idea preform: std::string str; std::ifstream in2("bigfile.txt", std::ios::binary); if (in2.is_open()) { in2.seekg(0, std::ios::end); str.reserve(in2.tellg()); in2.seekg(0, std::ios::beg); str.assign((std::istreambuf_iterator<char>(in2)), std::istreambuf_iterator<char>()); } for(size_t = 0; < str.size();i++) { if (str[i] == '\r') { str[i] = 0; } } then go through list , map vector of char* string. is there downfalls of design? and long don't delete char*'s shouldn't leak memory right? cause string loose scope , clear correct?

i have dictionary following structure: {('key1','key2'): 50, ('key3','key4'): 70, ('key1','key5'): 90.....} i want count in dictionary number of times 'key1' example appears first word in key tuple. i started writing below mentioned code not think further: count = 0 leng = 0 = 0 key1,key2 in range(1,len(bigrams)): count = count +1 leng = leng + (bigrams.get((key1,key2),0)) print(count) print(leng) any suggestion how should proceed ? from collections import defaultdict der = {('key1','key2'): 50, ('key3','key4'): 70, ('key1','key5'): 90} b = defaultdict(int) item, ler in der: b[item] += 1 print b ## defaultdict(int, {'key1': 2, 'key3': 1}) print b['key1'] ## [2] python tuple operations , count

i'm new threads , haven't written java in long time bear me here. have simple gui. has counter, status label, , 2 buttons, start , stop respectively. what wanted update status label using counter thread. when hit start supposedly starts counter @ 0 , increments every second , , when choose hit stop should suspend current thread , wait start button pressed again. whenever hit stop suspends waits second , resumes counting. when in reality want stay suspended. i'm not sure why it's doing that, tried searching before posting here got nothing. feel free criticize on you'd like. here's have: updated per @madprogrammer's answer. import java.awt.font; import java.awt.gridbagconstraints; import java.awt.gridbaglayout; import java.awt.event.actionevent; import java.awt.event.actionlistener; import javax.swing.jbutton; import javax.swing.jframe; import static javax.swing.jframe.exit_on_close; import javax.swing.jlabel; import javax.swing.swingutilities;
