for(int i=0;i<=10;i++) { driver.instance.find element(by.id("id of element")).send keys("auto"+i); } i used code not work 1 10 numbers printing in 1 attempt i searching code dynamically increment in each run out changing sendkeys values again , again your question not clear. trying enter value in 10 different edit boxes in single run or trying enter different values in same edit box in multiple runs (if can use random class generate random integers generate different values in different runs). random random = new random(); int = random.next(0, 10); driver.instance.find element(by.id("id of element")).send keys("auto"+i); you can increase bucket random.next(0, 10); random.next(0, 100); decrease probability of having same no in 10 runs.

i'm developing game using sprite kit , liquid fun (google's implementation of box2d liquids). after applied threshold shader make liquid more real, stumbled in strange behavior can seen on video: current behavior the way should behave can seen on video: normal behavior i'm applying shader on skeffectnode contains particles ( skspritenodes ) that's code on threshold shader: void main() { vec4 color = texture2d(u_texture,v_tex_coord); if(color.w > 0.4) { color = vec4(18.0/255.0, 122.0/255.0, 232.0/255.0, 1.0); } else { color = vec4(0.0, 0.0, 0.0, 0.0); } gl_fragcolor = color; } does have clue of going on?

i have function, working normally, on parse.com: parse.cloud.job ("mybgfunction", function(request, status) { console.log("entering mybgfunction."); }); but strange may seem, if update (saving , using parse deploy) usual following: parse.cloud.job ("mybgfunction", function(request, status) { console.log("entering mybgfunction (aaaa)."); }); the next time try execute, old function executed (in log), if update did go through, though got no error message after running: parse deploy has seen before? one more tiny question: there way clear old logs (on parse)? basic useful feature. looking bit more details @ happens classes, seems "all fine" except can see in log outdated. wrote earlier, logs previous versions. makes extremely difficult debug function, because trace-log becomes impossible. please go "cloudcode" section, , check if code same expected.
