java - How can I use Assert in Unit Testing? - 


package htmlunit;  import org.junit.assert;  import com.gargoylesoftware.htmlunit.webclient; import com.gargoylesoftware.htmlunit.html.htmlpage;  public class test {      public static void main(string[] args) throws exception {         final webclient webclient = new webclient();         final htmlpage page = webclient.getpage("http://htmlunit.sourceforge.net");         assert.assertequals("htmlunit - welcome htmlunit", page.gettitletext());          final string pageasxml = page.asxml();         assert.asserttrue(pageasxml.contains("<body class=\"composite\">"));          final string pageastext = page.astext();         assert.asserttrue(pageastext.contains("support http , https protocols"));          if(assert.asserttrue(pageastext.contains("support http , https protocols"))){             system.out.println("true");         } else {             system.out.println("false");         }          system.out.println("test");         webclient.closeallwindows();     } }

why run in eclipse, returns "test"? how can print results asserts?

        if(assert.asserttrue(pageastext.contains("support http , https protocols"))){             system.out.println("true");         } else {             system.out.println("false");         }

i have error:

type mismatch: cannot convert void boolean

how can use if assert?

assert.asserttrue void return. throws exception if input not true. useful in tests want crash indicate there problem.

looks in case want if(condition), not if(assert.asserttrue(condition)). don't have use case assert.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
