CasperJS / PhantomJS，某些测试随机失败

我有一些场景，其中某些测试随机地失败（可能是5/65），通常是svg，自动完成等。CPU很好，所以它来自于我编写脚本的方式。

但是我看不到如何更改它们以使其健壮可靠。这是我使用wait（）函数的时间->有时我遇到超时错误，有时它过去了。

最奇怪的是，当我将脚本分成两个脚本时，失败的次数少于一个..

添加waitForResource尝试

感谢Artjom B.的帮助。

casper.test.begin('\n********* Navigation on directories : ***********', 4,{
setUp: function(test) {
    setLevel("normal");
},

tearDown: function(test) {
    getJSON();
},

test: function(test){
    "use strict";
    var url = 'http://www.linternaute.com/';
    casper.start()
   .thenOpen(url + "/ville/", function(){
        if(this.exists('.ui-dialog-titlebar-close')){this.click('.ui-dialog-titlebar-close');}
        if(this.exists('#top_oas')){this.click('#top_oas > .right');}
        this.test.assertExists(".jODMainSearch", "Search toolbar present");

        this.clickLabel("Rennes (35000)");
    })
    .waitFor(function check() {
            return this.fetchText('h1').indexOf("Rennes") !== -1;
            }
            , function then() {
                this.test.assertSelectorHasText("h1", "Rennes");

    )
    //auto-completion

        /*** the changes ***/   
        this.waitForResource(function testResource(resource) {
            return resource.url.indexOf("http://static.ccmbg.com/www.linternaute.com/asset/js?m=odmainsearch") !== -1;
        }, function onReceived() {

        this.waitForSelector('ul.ui-autocomplete[viewbox="true"]', function() {
            this.mouse.move('a[href="/ville/rennes/ville-35238"]');
            this.click('a[href="/ville/rennes/ville-35238"]');
        });
    })
    .waitFor(function check() {

            }
            , function then() {
                this.test.assertSelectorHasText("h1", "Rennes");
            }
    )
    .run(function() {
            this.test.comment('--- Done ---\n');
            test.done();
    });
}
});

第一次尝试 ：

这是一个随机失败的例子：

casper.test.begin('\n********* Navigation on directories : ***********', 4,{
setUp: function(test) {
    //setLevel("normal");
},

tearDown: function(test) {
    //getJSON();
},

test: function(test){
    "use strict";
    var url = 'http://www.linternaute.com/';
    casper.start()
   .thenOpen(url + "/ville/", function(){
        //close some ads
        if(this.exists('.ui-dialog-titlebar-close')){this.click('.ui-dialog-titlebar-close');}
        if(this.exists('#top_oas')){this.click('#top_oas > .right');}
        this.test.assertExists(".jODMainSearch", "Search toolbar present");
        this.sendKeys(".jODMainSearch", "Ren");
        this.click(".submit.search");
    })
    .waitForSelector(".odListGlossary", function(){
        this.test.assertExists(".odListGlossary", "Search result ok");
        this.clickLabel("Rennes (35000)");
    })
    .waitFor(function check() {
            return this.fetchText('h1').indexOf("Rennes") !== -1;
            }
            , function then() {
                this.test.assertSelectorHasText("h1", "Rennes");
            }
    )
    //auto-completion
    .thenOpen(url + "/ville/", function(){
        this.sendKeys('.jODMainSearch', 'Ren', {keepFocus: true});
        this.waitForSelector('ul.ui-autocomplete[viewbox="true"]', function() {
            this.mouse.move('a[href="/ville/rennes/ville-35238"]');
            this.click('a[href="/ville/rennes/ville-35238"]');
        });
    })
    .waitFor(function check() {
            return this.fetchText('h1').indexOf("Rennes") !== -1;
            }
            , function then() {
                this.test.assertSelectorHasText("h1", "Rennes");
            }
    )
    .run(function() {
            this.test.comment('--- Done ---\n');
            test.done();
    });
}
});

而且，如果我只看脚本的结尾（在第一个示例中它随机失败，那么我已经注释了开头）：

casper.test.begin('\n********* Navigation on directories : ***********', 1,{
setUp: function(test) {
    //setLevel("normal");
},

tearDown: function(test) {
    //getJSON();
},

test: function(test){
    "use strict";
    var url = 'http://www.linternaute.com/';
    casper.start()
   /*.thenOpen(url + "/ville/", function(){
        if(this.exists('.ui-dialog-titlebar-close')){this.click('.ui-dialog-titlebar-close');}
        if(this.exists('#top_oas')){this.click('#top_oas > .right');}
        this.test.assertExists(".jODMainSearch", "Search toolbar present");
        this.sendKeys(".jODMainSearch", "Ren");
        this.click(".submit.search");
    })
    .waitForSelector(".odListGlossary", function(){
        this.test.assertExists(".odListGlossary", "Search result ok");
        this.clickLabel("Rennes (35000)");
    })
    .waitFor(function check() {
            return this.fetchText('h1').indexOf("Rennes") !== -1;
            }
            , function then() {
                this.test.assertSelectorHasText("h1", "Rennes");
            }
    )*/
    //auto-completion
    .thenOpen(url + "/ville/", function(){
        this.sendKeys('.jODMainSearch', 'Ren', {keepFocus: true});
        this.waitForSelector('ul.ui-autocomplete[viewbox="true"]', function() {
            this.mouse.move('a[href="/ville/rennes/ville-35238"]');
            this.click('a[href="/ville/rennes/ville-35238"]');
        });
    })
    .waitFor(function check() {
            return this.fetchText('h1').indexOf("Rennes") !== -1;
            }
            , function then() {
                this.test.assertSelectorHasText("h1", "Rennes");
            }
    )
    .run(function() {
            this.test.comment('--- Done ---\n');
            test.done();
    });
}
});

那么问题是什么，您有想法吗？->堆栈中有两个步骤函数：通常会失败，只有一个：有时会失败...
